I WAS THINKING "\[B\]" IS THE ANSWER!

Answer 2

Nevermind, the answer is D. Correct? @Abhisar

Answer 3

I thought beta was also an answer, so I chose B in the first place...

Answer 4

Positron emission is a decay in which proton gets converted into a neutron and a positron and a neutrino is emmited

ex: \(\sf Mg → Na + e+ + ν_e\)

Notice that mass number of both the elements are same i.e 23.

Answer 5

Same thing happens in beta decay.

Answer 6

got it ?

Answer 7

so B was correct?

Answer 8

yes
