I think b is correct ....

Answer 2

Answer:

The correct option is (B) Protons and Neutrons.

Explanation:

• Protons, electrons, and neutrons are subatomic particles of an atom.
• Protons and neutrons are always present in the nucleus of an atom, while electrons revolve around the nucleus. Electrons can never be seen in the nucleus.
• The diameter of protons and neutrons is nearly the same. Their atomic mass unit is 1.
• The mass of an electron is $\frac{1}{2000}$ of the mass of a proton and a neutron. It has a negligible mass.
• The proton carries a positive charge and the electron carries a negative charge.
• Neutrons carry no charge at all; they are neutral.
