The verified response to “Ancient History question: Which one of the following was a major feature of Harappan religion?” is Fertility and nature-related cults, option C. The original question-specific evidence states: Mother Goddess figures, trees and animal motifs suggest fertility and nature-related worship. Fertility and nature-related cults is the correct answer to “Which one of the following was a major feature of Harappan religion”. This evidence connects the required Ancient History fact with its archaeological, geographical, cultural or chronological setting. Harappan evidence must be interpreted from excavated settlements, artefacts, environmental data and comparisons among sites; a single object should not automatically support a wider claim than the evidence permits. The choices Islamic shrines, Buddhist monasteries and Ashvamedha sacrifice do not satisfy the same combination of site, feature, river region, crop, craft, discovery, chronology or cultural association. The attribution is presented as an exam-oriented historical identification and should be read within the archaeological context stated in the question. A reliable check begins by identifying the question type: location, site feature, archaeological find, economic activity, urban planning, chronology or interpretation. Then compare the chosen answer with the relevant NCERT theme and reject options belonging to another site or category. Replaying that method confirms Fertility and nature-related cults as the keyed response for this Ancient History question. This evidence-led approach strengthens factual recall, chronological caution and option elimination for SSC, Railway, Banking, Defence, State and other competitive examinations.
