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.

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
