`._(37)^(81)Rb+ ._(-1)e^(0)to ._(36)^(81)Kr`

Options

A. The process is called `K`electron capture
B. The process gives out radiations called `gamma`-rays
C. The process gives out radiations called `X`-rays
D. `Rb` nucleaus accepts of the `1s`-electron and one proton to give rise to the formation of one neutron
