Label 1: Photon
Label 2: Positron
Label 3: No change in mass number

Which is the best region for each label?

A. Label 1: Z
Label 2: X
Label 3: Y
B. Label 1: X
Label 2: Z
Label 3: X
C. Label 1: X
Label 2: Z
Label 3: Y
D. Label 1: X
Label 2: Z
Label 3: Z

Answer 1

The answer is C
Label 1: X
Label 2: Z
Label 3: Y

Answer 2

Answer:

C. Label 1: X

Label 2: Z

Label 3: Y

Explanation:

A gamma ray is an electromagnetic radiation that can also exist as a photon. It is often referred to as a high energy photon. Secondly, a positron is one of the types of a beta particle. Lastly, the emission of either gamma or beta does not have any effects on the mass number of the radioactive material. Therefore, the correct order of arrangement/label is:

Label 1: X

Label 2: Z

Label 3: Y
