Answer

Brief Explanations:

Region X represents characteristics exclusive to Gamma Decay. Gamma decay involves the emission of a photon from an excited nucleus. Therefore, Label 1 (Photon) belongs in region X. Region Z represents characteristics exclusive to Beta Decay. Beta decay involves the emission of an electron or a positron. A positron is emitted during beta-plus decay. Therefore, Label 2 (Positron) belongs in region Z. Region Y represents characteristics common to both Gamma Decay and Beta Decay. In both types of decay, the mass number (total number of protons and neutrons) of the nucleus does not change. Therefore, Label 3 (No change in mass number) belongs in region Y.

Answer:

Label 1: X, Label 2: Z, Label 3: Y
