Solution

The correct option is B
Statements 1 and 2 are true but statement 2 is not the right explanation of statement 1

Both the statements are true.
Except for hydrogen which has no neutron has 1 proton. All other atoms have neutrons $\geq$ protons.
In any neutral atom, the number of electrons is equal to the number of protons. That is the reason that a neutral atom atom has no charge on it.
