Solution

The correct option is A

BD


Given Two circles with centres P and Q intersect each other at A and B. CBD is a line segment and EBM is tangent to the circle with centre Q, at B. Radii of the circles are equal.

Construction - Join AB and AD

Proof - EBM is the tangent and BD is the chord

DBM=BAD (Angles in alt. segment)

But DBM=CBE

(Vertically opposite angles)

BAD=CBE

In the same circle congruent circles, if angles are equal, then chords opposite to them are also equal.

CE=BD
