Which symbol represents a beta particle?

Explanation:
Beta particles are electrons emitted during beta decay. They carry a negative charge and have nearly zero mass compared with protons and neutrons. The symbol −₁⁰e encodes this: a negative charge, mass number 0, and the particle is an electron. The other symbols match other particles—a helium nucleus for an alpha particle, a neutron, and a proton. So the electron symbol is the beta particle.
