Answer :-

Option B. An atom has equal number of protons and electrons.

☆ Reason :-

An atom is always neutral in charge. This means that an atom doesn't carries any charge neither negative (more electrons) nor positive (more protons). It hence proves that number of negative charges balances the number of positive charges, leading to atom being neutral.
