Vedclass · Answer

(B) By definition,isobars are atoms of different elements that have the same mass number $(A)$ but different atomic numbers $(Z)$.Therefore,the Assertion is correct.Protons and neutrons are indeed present inside the nucleus,which is a correct statement regarding nuclear composition.However,the fact that protons and neutrons exist in the nucleus does not explain why certain atoms are isobars.Thus,the Reason is a correct statement but is not the correct explanation for the Assertion.

Assertion: Isobars are the elements having same mass number but different atomic number.
Reason: Neutrons and protons are present inside the nucleus.
