Correct answer: (D) Brother's daughter
B%C: B is sister of C; C?O: C is daughter of O; O€P: O is son of P; P=X: P is father of X. So O and X are both children of P (siblings), and B, being O's sister, is the daughter of O's father — making B the 'brother's daughter' of X.

सही उत्तर: (D) MJ -
B%C: B, C की बहन है; C?O: C, O की पुत्री है; O€P: O, P का पुत्र है; P=X: P, X का पिता है। अतः O और X दोनों P की संतान हैं (सहोदर), और B, O की बहन होने के कारण, O के पिता की पुत्री है — इस प्रकार B, X के लिए 'भाई की पुत्री' है।
