Solution

The correct option is B
2

The explanation for the correct option:
Option B
Isotopes are atoms that have the same number of protons but differ in the number of neutrons.
Isotopes are elements with the same atomic number but distinct mass numbers
Because the atomic number equals the number of protons and the atomic mass equals the sum of protons and neutrons.
There are three isotopes of Hydrogen, Protium, Deuterium, and Tritium.
They have the same protons but differ in neutrons.
In Protium there are zero neutrons, Deuterium has 1 neutron and Tritium has 2 neutrons.
Hence Option B(2) is a correct Option.
