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

Assertion (A)

Reason (R)

If a ray stands on a line such that ∠ACD = ∠BCD, then ∠ACD = 90°.

If a ray stands on a line then ∠ACD + ∠BCD = 180°.

According to linear pair of angle, sum of angles on straight line is 180

And 90 + 90 = 180^o
