none of these

Explanation:
Detailed explanation-1: -Beta minus particle (-) emission occurs when the ratio of neutrons to protons in the nucleus is too high. An excess neutron transforms into a proton and an electron. The proton stays in the nucleus and the electron is ejected energetically.
Detailed explanation-2: -Beta decay When a nucleus emits a beta particle, these changes happen: the mass number stays the same. the atomic number increases by 1. the nuclear charge increases by 1.
Detailed explanation-3: -In beta-minus decay, a neutron breaks down to a proton and an electron, and the electron is emitted from the nucleus.
Detailed explanation-4: -The emission of beta radiation provides evidence that neutrons and protons are made up of quarks.
