Answer:
As in alpha decay mass number of parent nucleus decreases by 4 and atomic number decreases by 2 so the right nuclear equation is as

The chemical equation which represents an alpha decay is ²⁴¹A₉₅ ----> ²³⁷N₉₃ + ⁴He₂.
What is an alpha decay?
An alpha decay can be defined as a type of radioactive decay in which the atomic nucleus of a radioactive element emits an alpha particle, thereby, producing chemical elements with a different atomic nucleus.
Basically, the radioactive element has a mass number that is decreased by four (4) and an atomic number that is decreased by two (2), which is an atom of Helium (He).
