• B. neutrons
• C. electrons
• D. neutrinos

Answer 1

The correct option is A

protons

Protons

The proton is a subatomic particle, symbol p or p+, with a positive electric charge of +1e elementary charge and mass slightly less than that of a neutron. Since neutron has no charge, proton has +1e elementary charge, the positive charge on the nucleus is due to the presence of protons in it.
