Solve step-by-step :

1. A is the spouse of B: So, A and B are married. – (A और B पति पत्नी है )
2. B has no female child: This means B has only male children, no daughters. – (A और B के केवल लड़के है )
3. C is the brother of D and E: C, D, and E are siblings, and C is a male (since he is a brother). ( C, D, और E भाई -भाई है)
4. E is the son of B: E is confirmed to be B’s son. Since B has no female child, C and D must also be sons. ( E, B का लड़का है – C और D भी B के लड़के है )
5. A is not the mother of D: This implies that D’s mother is someone other than A. Therefore, D could be B’s son from a previous relationship.
   (A, D की माँ नहीं है – तो A, D का पिता होगा – B – C, D, और E की माँ है )

Conclusion:

D is B’s son because B has only male children, and there’s no indication that D is anything other than a son. So, D is related to B as his son.
B, D की माँ है, इसलिए D, B का पुत्र होगा l
