Which equation or equations represent beta decay?

C

A and D

D

A and B

B

A

C and D

A and D

Explanation:

I just took a test an got it right.

Answer: (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.
