Correct option a) Both Assertion and Reasoning are true, and Reasoning is the correct explanation for Assertion.

The atomic number (Z) of an atom is equal to its number of protons, but the atomic mass number (A) of an atom is equal to the sum of its protons and neutrons. Isobars have the same atomic mass number but different atomic numbers because they have the same number of neutrons but different numbers of protons. Therefore, both the Assertion and Reasoning are true, and Reasoning is the correct explanation for Assertion.
