Blood relation reasoning concepts – UGC NET Question

Statements A, C and E correctly describe blood relation terminology and strategy. A is true because maternal and paternal terms indicate sides of the family. C is correct since drawing family trees is a widely recommended method for organizing information. E accurately defines “son-in-law” as the husband of one’s daughter. B is false, as B’s gender is not specified by A being a brother of B, and D is false because siblings include both brothers and sisters. Thus A, C and E only are correct.

Option A:
Option A is correct because it includes the precise conceptual statements about terminology and problem-solving strategies while excluding B and D, which misrepresent gender implications and the definition of siblings. It reflects the conventions used in NET reasoning questions.

Option B:
Option B is incorrect as it adds B, wrongly asserting that B must be male when A is B’s brother, and therefore introduces a false assumption into the set of correct statements.

Option C:
Option C is wrong because it includes D, which incorrectly narrows “siblings” to brothers only, so the combination mixes correct and incorrect statements.

Option D:
Option D is incorrect since it omits A and adds B, losing a key distinction between maternal and paternal relations and at the same time accepting a wrong inference about B’s gender.
