Each question consists of two statements, namely, Assertion (A) and Reason (R). Choose the correct option.

Assertion (A)

Reason (R)

If two lines AB and CD intersect at O such that ∠AOC = 40°, then ∠BOC = 140°.

If two straight lines intersect each other, then vertically opposite angles are equal.

Because when two lines intersect each other, then vertically opposite angles are always equal.
