- Jaya and Kishore → married couple
- Their sons → Mohit and Naval
- Binita is daughter-in-law of Kishore → so she is married to Mohit or Naval
- Binita is also daughter of Mahesh → so Mahesh is Binita’s father
- Therefore, Mohit must be Mahesh’s son-in-law
So, the correct relation is: Mohit is son-in-law of Mahesh
