Assertion (A) : The circle x² + y² = 1 has exactly two tangents parallel to the x-axis
Reason (R) : dy/dx= 0 on the circle exactly at the point (0, ±1) of these statern ents

A. Both A and R are true but R is not the correct explanation of A

B. Both A and R are true and R is the correct explanation of A

C. A is true but R is false

D. A is false but R is true

E. None of the above

View Answer

Correct choice: B

Explanation:

Both the sentences are true and R is the correct explanation of A, because for tangents which are parallel to x- axis, dy/dx=0 .
