If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.

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.

List-$I$	List-$II$
$(A)$ Strong nuclear force	$(i)$ $10^{-2}$
$(B)$ Weak nuclear force	(ii) $1$
$(C)$ Electromagnetic force	(iii) $10^{-39}$
$(D)$ Gravitational force	(iv) $10^{-13}$

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