Therefore that only son must be Rohan himself. The pointed girl is the daughter of that only son, so she is Rohan's own Daughter. Cousin is wrong because a cousin would be the child of an aunt or uncle, but no such branch is described. Sister is wrong because a sister would be in Rohan's generation, whereas the girl is one generation below the only son. Niece is wrong because a niece is a sibling's daughter; here the girl is Rohan's own daughter. The chain is: Rohan's father → only son = Rohan → that son's daughter = Rohan's daughter. The word 'only' removes the possibility of another male sibling. Reversing the relation, Rohan is the girl's father, confirming Daughter uniquely.

Blood Relation in Logical Reasoning tests the ability to understand family relationships between people. Questions involve identifying the relationship between two members of a family based on given clues. Common relationships include father, mother, brother, sister, uncle, aunt, cousin, nephew, and niece. It is asked in SSC, Bank PO, and Railway exams.
Tips to solve Blood Relation questions: Draw a family tree diagram, Use symbols (plus for male, minus for female), Start from the reference person, Trace relationships step by step, Be careful about gender (maternal/paternal). Practice 20-30 questions daily to master this topic for competitive exams.
Types of Blood Relation questions: Direct questions (A is B father, what is B to A?), Coded relations using symbols like + - * /, Sitting arrangement with relations, Series-based family relations, and Gender-based confusion questions. SSC CGL, IBPS PO, and RRB exams commonly ask these types.
Maternal relations are from the mother side: maternal uncle (mama), maternal aunt (mausi), maternal grandfather (nana), maternal grandmother (nani). Paternal relations are from the father side: paternal uncle (chacha/tau), paternal aunt (bua), paternal grandfather (dada), paternal grandmother (dadi). Distinguishing these is key to solving Blood Relation problems.
Common mistakes in Blood Relation questions: Assuming gender when not given, Confusing maternal and paternal relations, Not drawing a proper family tree, Misinterpreting coded symbols, Rushing without reading all clues. Always draw a family tree and verify the final relationship to avoid errors in competitive exams.
