Explanation / Answer

1.

in HCN

Carbon attached with H with single bond

and sme carbon attached with nitrogen in triple bond

all the atoms valency is satisfied

option B is correct answer

2.

carbon valancy is 4 and O valency is 2

in given structure C is habing only 4 bonds so 0 charge

but oxygen si having one bond extra so it carries +1 charge

option C is correct answer.

3.
