Option 4 : Only Il follows.

Least possible Venn diagram:

[ alt="F1 Savita Railways 6-5-22 D25" src="//storage.googleapis.com/tb-img/production/22/05/F1_Savita_Railways_6-5-22_D25.png" style="width: 325px; height: 165px;">

Conclusions:

I. All children who go to coaching are brilliant → Doesn't follow (As per the Venn diagram there is no direct relation between children who go to coaching and brilliant children so we can not say that all children who go to coaching are brilliant or not)

II. Children who go to coaching also study in class V → Follow (As per the Venn diagram there is a direct relation between children who go to coaching and study in class V, so we can say that this conclusion is true).

III. All children who study in class V are not brilliant → Doesn't follow (As per the Venn diagram there is a direct relation between all children who study in class V and brilliant children and we can say that all children who study in class V are not brilliant it can be possible but not definite, hence false)

So, only conclusion II follows.

Hence, the correct answer is "Option 4" .
