A:

S-block consists of two groups.

That means in any period, there are two electrons which can fit in s shell.

Hence, from 2 to 7 periods, there are two groups in every periods for s-block.

Similarly, there are 10 groups for d-block as 10 electrons can occupy d-block.

Also, in the same way, there are 6 groups in p block as total 6 electrons can occupy p subshells.
