If an element X of an atomic number Z and mass number Y is irradiated by an intense concentration of neutrons, the relevant nuclear equation is?
yzX + 10n → y - 1z + 1X
yzX + 10n → y + 1zX
yzX + 10n → yz + 1X
yzX + 10n → y + 1z - 1X

the correct answer is B
for mass number Y we have
Y+1 = Y+1
and Atomic number Z we have
Z+0 = Z
therefore we will obtain
option B 

Here's a clarification 👇
"To Emit" (give off) is quite different from "to irradiate" (absorb typically when struck)
Normally when an atom emits neutron, it's atomic mass decrease by 1 and atomic number remains same (as subtracting 0 will not add any value) ...
But when an atom is irradiated (struck) by a neutron it absorbs it, making the atomic mass increase by 1 and atomic number remains same ( as plus 0 will not add any value)...
This irradiation process is also known as neutron capture. We also have alpha capture, Beta capture and others depending on the particle that struck...

I think the answer should be c because beta decay usually have a high concentration of neutrons
