Option 2 : A
The combinations are:
Rahul + Kusum = Hindi + Maths------ (i )
Sameer + Rahul = Hindi + Biology-------(ii)
Gita + Kusum = Marathi + Maths-------(iii)
Sameer + Gita + Mihir = History + Biology-------(iv)
There can be two possible combinations for Marathi and Biology:
Using (ii) and (iii)
Sameer + Rahul = Hindi + Biology-------(ii)
Gita + Kusum = Marathi + Maths-------(iii)
But here no one is common so we cannot determine that person who is good in both Marathi and Biology.
Using (iii) and (iv)
Gita + Kusum = Marathi + Maths-------(iii)
Sameer + Gita + Mihir = History + Biology-------(iv)
Here Gita is common, so Gita is good in both Biology and Marathi.
