Both (a) and (b)
None of these​

Answer 1

It does not matter much

Answer 2

Answer:

Does

Explanation:

Because 'it' refers to a single thing so 'do' is not possible as do is used with plural nouns; since (a) is not correct hence (c) is also not correct. Now, (b) is correct because the sentence makes sense and is grammaticality correct if we use it. Hence, (d) is also not correct. And, we are left with (b) only.
