Final Deduction
As P is the daughter of T's paternal aunt, P is the daughter of the father's sister.
A: Sister's daughter is incorrect as P is not the daughter of T's own sister. B: Father's daughter is incorrect as P is the daughter of the father's sister. C: Father's mother is incorrect as P is a younger generation member.
D is correct because P is the daughter of R, and R is the sister of T's father (Q), making P the daughter of T's father's sister.
