Solution

The correct option is A A, B and C are isobars
Isobars are atoms of different chemical elements that have the same number of nucleons. Correspondingly, isobars differ in atomic number (or number of protons) but have the same mass number

$α$ contains 2 protons and 2 neutrons. mass no. is 4
$β$ contains 1 electron. no mass no.

When $α$ particle is released from X, mass no. is reduced by 4. from then only $β$ particles are released which has no effect in mass no. as there is no mass no. in $β$ particle.
So A, B and C contain same mass no. which are called isobars, but there is change in atomic number so these cannot be isotopes.
