Examine the following equations.

a. 23490th→23491pa+0−1e+γ

b. 60∗27co→6027co+γ

c. 23490th→23088ra+42he

d. 146c→147n+0−1e

which equation or equations represent beta decay?

c
a and d
d
a and b
b
a
c and d

(A) and (D)

Options (A) and (D) represent beta decay.

Explanation:

It is very simple to find  beta decay in a nuclear reaction. In beta decay , neutron breaks down into a proton and an electron. After that electron is emitted from the nucleus,while proton remains inside nucleus. The resulting daughter nuclei will have one more proton and one less neutron.
