Answer 2

Answer: D) it usually accompanies beta or alpha radiation..

Explanation:-

Gamma decay : In this process, the unstable nuclei transformed into stable nuclei by releasing gamma rays along with beta or alpha decay. It is observed when a nucleus is formed in an excited state and then decays to its ground state by emitting an electromagnetic radiation.

General representation of an element is given as:   $_Z^A\textrm{X}$

where,

Z represents Atomic number

A represents Mass number

X represents the symbol of an element

General representation of gamma decay :

$_Z^A\textrm{X}^*\rightarrow _Z^A\textrm{X}+_0^0\gamma$
