Assertion `H_(2),Li_(2),B_(2)` each has a bond order of 1 and hence are equally stable
Reasoning Stability of molecule//ion depends only on bond order .

Options

A. If both `(A)` and `(R )` are correct and `(R )` is the correct explanation of `(A)`
B. If both `(A)` and `(R )` are correct and `(R )` is the correct explanation of `(A)`
C. If `(A)` is correct but `(R )` is incorrect
D. If both `(A)` and `(R )` are incorrect

Explanation

Correct `(A) : H_(2),Li_(2)` and `B_(2)` are not equally stabel Correct `(R )` The stability of molecules//ions does not depend only on bond order It also depends upon other factors like bond length number of `e^(-)` s present in `ABMO` s etc .
