Kalyani is Ashok’s mother.

Step-by-step reasoning

  • Veena is the sister-in-law of Ashok.
  • Veena is also the daughter-in-law of Kalyani, so Veena is married to Kalyani’s son.
  • Dheeraj is the father of Sudeep, who is the only brother of Ashok.
  • Since Veena is Ashok’s sister-in-law and Ashok has only one brother (Sudeep), Veena must be married to Sudeep.
  • Kalyani is mother-in-law of Veena, so she is Sudeep’s mother, and because Sudeep and Ashok are brothers, Kalyani is also Ashok’s mother.

So, in the blood relation sense, Kalyani is the mother of Ashok (even if some MCQ options list the answer as “None of these” because “Mother” is not among the choices).

TL;DR: Kalyani is related to Ashok as his mother.
