Find the incorrect sentence :

A He knows in and out of that affair.

B He made light of his friend's warning.

C The child was as good as gold.

D I took him to task for his carelessness.

Correct Answer: Option A

ভুল বাক্যটি হলো : He knows in and out of that affair । In and out-এর স্থলে Ins and outs ( খুঁটিনাটি ) হলে বাক্যটি সঠিক হতো ।
