Answer

Explanation:

Step1: Recall gamma - decay properties

Gamma decay involves the emission of a photon. Gamma decay occurs when a nucleus is in an excited state and transitions to a lower - energy state by emitting a gamma ray (photon). So, the photon is associated with gamma decay, which is region X.

Step2: Recall beta - decay properties

Beta - plus decay involves the emission of a positron. Beta decay is represented by region Z.

Step3: Recall decay and mass - number relationship

In both gamma and beta decay, there is no change in the mass number. Gamma decay just releases energy in the form of a photon without changing the number of protons or neutrons. In beta - plus decay, a proton changes to a neutron and a positron is emitted, but the sum of protons and neutrons (mass number) remains the same. The overlapping region Y represents the property that is common to both gamma and beta decay, which is no change in mass number.
