Question

"Sidda said giving a stock reply "-what is a "stock reply"?

Answer 1

Answer:

a "stock reply" is an answer that one is habituated to giving. It is a standard reply and it is expected that the person would give that reply, most of the times.

Explanation:

Possibly the origin has come from the term "stock". It could mean that a "stock reply" is always available (it is always in stock) and is hence used very often.
