Answer 2

Answer:

QUARKS

Explanation:

Quarks are usually defined as a small particle that binds up protons and neutrons by a strong force of attraction. These form the fundamental particles in physics.

There are mainly six types of quarks and they are as follows-

top, bottom, up, down, strange, and charm
