If XY is a tangent to a circle with centre O at point P, then $OP$ is
Aparallel to XY
Bperpendicular to XY
Cequal to XY
Da tangent to XY
Answer & Solution
Correct answer: B. perpendicular to XY
By the tangent-radius theorem, the tangent at any point of a circle is perpendicular to the radius through the point of contact. Therefore $OP \perp XY$.
