Option (b) is the correct answer.

Explanation:

A positively charged particle that consists of two protons and two neutrons is known as an alpha particle.

The symbol for alpha particle is . An alpha particle is similar to a helium atom because helium atom also has mass number (number of protons + number of neutrons) as 4 and atomic number (number of protons) as 2.

Symbol of helium atom is .

Thus, we can conclude that an alpha particle is also referred to as a nucleus of helium isotope.
