Which disease is caused by deficiency of Vitamin C?

Last Updated: 26 Jun 2026

This question examines a fundamental concept of human anatomy, physiology, health, nutrition, disease, or body regulation that frequently appears in SSC CGL General Science. Questions may also test blood components, vitamins, glands, sense organs, communicable diseases, and deficiency disorders. A familiar word is not automatically correct; qualifiers such as “largest,” “primary,” “deficiency,” “secreted by,” “carries,” or “controls” determine the answer. Restate the question in your own words, predict the answer before checking the options, and confirm that the explanation and correct-option field both point to Scurvy.

Correct Answer: ScurvyYour Answer: C

Explanation

ce–function or deficiency–disorder pair and eliminate neighbouring concepts. Do not confuse an organ that produces a substance with an organ on which that substance acts, or a vector with the organism that causes a disease. Therefore option C, Scurvy, is factually consistent with the stem, the marked correct index, and the explanation.✅ Correct Answer: C — Scurvy Scurvy is caused by deficiency of Vitamin C (Ascorbic Acid). Vitamin C is essential for the synthesis of collagen protein. Historically, sailors suffered from scurvy due to lack of fresh fruits. Rickets — Caused by deficiency of Vitamin D (or calcium/phosphorus); leads to weak, soft bones in children. Pellagra — Caused by deficiency of Vitamin B3 (Niacin); characterized by 3 Ds: Dermatitis, Diarrhea, Dementia. Beri-beri — Caused by deficiency of Vitamin B1 (Thiamine); affects the nervous system and heart. 📝 Important Note: Vitamin C deficiency = Scurvy. Vitamin D deficiency = Rickets. Vitamin B1 deficiency = Beri-beri. Vitamin B3 deficiency = Pellagra. Citrus fruits are the best source of Vitamin C.

Important Notes

ecord is Scurvy, corresponding to option C. The answer field, correct index, and both explanations must remain aligned.
Read the complete stem and identify the exact demand: organ, gland, hormone, cell, tissue, nutrient, enzyme, pathogen, vector, deficiency disease, body fluid, or physiological function.
Learn nutrition facts as nutrient–source–function–deficiency pairs. Vitamins and minerals can have several roles, but SSC questions usually ask the best-known primary association.
Rickets, Pellagra, Beri-beri are eliminated here because none satisfies the precise requirement of the stem. Practising the reason for each rejection is more reliable than memorising only the correct choice.

FAQ

SSC CGL Human Body FAQs

Common questions and clear answers for this topic.

Which body systems are most important for SSC CGL preparation?

The digestive, circulatory, nervous, and skeletal systems appear most frequently, along with sensory organs and basic endocrine functions.

How many bones are there in the human body, and is this commonly asked?

Yes, the human body has 206 bones, and questions about the largest, smallest, and total bone count appear fairly often.

What kind of blood-related questions come up in SSC CGL?

Questions usually cover blood group compatibility, the role of platelets in clotting, and basic facts about blood pressure and heart function.

Do I need detailed biochemistry knowledge for the human body section?

No, most questions focus on what each organ does and why, rather than the detailed biochemical processes behind it.

How can I retain human body facts more effectively for the exam?

Linking facts to real-life observations, like why pulse is checked at the wrist, makes them easier to recall than memorizing textbook lines.
