ASSERTION

$$a$$ and $$b$$ are forming a linear pair.

REASON

$$a$$ and $$b$$ are forming a pair of adjacent angles.


ANSWER

Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion


SOLUTION
As we see, $$\angle AOC $$ and $$\angle BOC$$ have a common vertex $$O$$. So, $$a$$ and $$b$$ are adjacent angles
And $$OB$$ and $$OA$$ are opposite rays.
So, $$a$$ and $$b$$ are linear pair that means their sum is $$180^{\circ}$$.
But, adjacent angles does not necessarily add up to give $$180^{\circ}$$, it can give any sum.
So, reason is not correct explanation.
Hence, option $$B$$ is correct.
