Answer 1

A beta particle is an electron emitted by a radioactive nucleus. In beta decay, one of the neutrons in the nucleus suddenly changes into a proton, causing an increase in the atomic number of the parent element.
$_{z} A^{m} \to_{z + 1} B^{m} +_{- 1} e^{0}$

Hence, option $D$ is correct.

Answer 2

A beta particle is an electron emitted by a radioactive nucleus. In beta decay, one of the neutrons in the nucleus suddenly changes into a proton, causing an increase in the atomic number of the parent element.

_{z} A^{m} \to_{z + 1} B^{m} +_{- 1} e^{0}

Hence, option

D

is correct.
