Answer: Option (A) is the correct answer.
Explanation:
It is know that each element consists of three sub-atomic particles. These are protons, neutrons and electrons.
Inside the nucleus of an atom, there will be only protons and neutrons. Whereas electrons revolve around the nucleus of an atom.
Protons have a positive charge, neutrons have no charge and electrons have a negative charge.
Therefore, we can conclude that electrons are the subatomic particles which are found in the space surrounding an atoms nucleus.
