Answer:
(A) BD
Step-by-step explanation:
Given: A circle with center O.
To find: Determine the segment which is secant.
Solution: From the given figure, A circle with center O is given.
A secant is a line that intersects the circle in two different points and a tangent is a line that intersects the circle in exactly one point, called the point of tangency.
Thus, in the given figure, OA is the represented as the radius of the circle, EF is represented as the chord of the circle and BC is the tangent by the definition of the tangent.
Thus, BD is represented as secant of the circle because BD is the only segment which is intersecting the circle at two different points.
