UGCNET Questions

P is stated to be the father of Q, so Q is P’s child. Q is the mother of R, so R is Q’s child. This makes R the grandchild of P through Q. Since P is male, his relationship to R is that of a grandfather. The reasoning follows the generational links step by step.

Option A:
Option A correctly identifies that P stands two generations above R: P → Q → R. Being the father of R’s mother, P is the maternal grandfather of R. This matches both the gender information and the generational structure.

Option B:
Option B, father, would mean P directly parents R, but the question clearly states that Q is the mother of R, not P.

Option C:
Option C, uncle, would require P to be a sibling of R’s parent, which is not the case here because P is Q’s father, not Q’s brother.

Option D:
Option D, brother, would place P in the same generation as Q and R, which contradicts the given description that P is Q’s father.

A is given as the mother of B. B and C are siblings because B is the brother of C, so A is also the mother of C. C is the father of D, which means D is A’s grandchild through C. Hence, combining these links, A’s relationship to D is that of a grandmother.

Option A:
Option A correctly traces the family relations step by step: A is parent to C, and C is parent to D, making A one generation above D’s parent. This is precisely the definition of a grandparent, and since A is female, the correct term is grandmother.

Option B:
Option B, aunt, would be appropriate if A were a sibling of D’s parent, but the problem clearly states A is the mother of B and C, not their sister. Therefore, she stands one generation above, not at the same generation as D’s parent.

Option C:
Option C, sister, would require A and D to share the same parents or at least be in the same generation. The information places A two generations above D, so this description is incompatible.

Option D:
Option D, mother, would mean A directly gave birth to D, but the statement shows that C is the father of D, and A is C’s mother, so the relationship has an extra generational step.
