Hint: We must know that the number of protons and electrons in any atom is always the same. There are many protons present. Hydrogen has three protons all of them have the same number of protons and electrons. What makes them different is their atomic masses. Atomic masses play a very important role.

-We need to remember that the isotopes have an equal number of protons and electrons present. It depends on the atomic mass number.
-We must know that the atomic mass number which is denoted by A plays a very important role. Atomic mass number is the sum of neutrons and protons that are present in the nucleus of an atom. The number of electrons and protons are always equal.
-Atomic number depends on the number of protons or electrons, it is denoted by Z. Z plus number of neutrons is equal to mass number. Mass number plays are necessary for an isotope.
-So isotopes depend on the number of Protons and neutrons present in an Atom.
-Isotopes are very useful in the field of science.
-Hence an isotope has the same number of protons and electrons and it also has different neutron isotopes depending on their atomic mass number.
-Isotopes of hydrogen have different atomic mass numbers which are 1, 2, 3. But they have the same atomic number which is 1.
-Option A is correct as isotopes do have the same number of electrons and protons.
-Option B is also correct as there is a difference between v the number of neutrons in various isotopes.
-Option C is also right because isotopes depend on their atomic mass number
-Option D says all of these which is the actual answer because all of the above are correct statements for isotopes.
And hence option D is the right answer.

Note:
We must know that by changing the number of neutrons it does not change or can even affect the chemistry of the element present. The reason is neutrons are neutral which means that they have no charge. Isotopes are usually identified by their mass that is the total number of protons and neutrons in the nucleus of an atom.
