Solution

The correct option is B

False


Let us draw the points A, B, C, D such that ACB =ADB.

Now, draw a circle through A, B, C. Let us assume that the circle does not pass through the point D but intersects the extension of line segment CD at D.

Since, angles subtended by an arc in a segment are equal, ACB =ADB. It is given that ACB =ADB. Thus, for the angles to be equal, D and D should coincide. Thus, our assumption that the circle does not pass through D is wrong.

Therefore, only one circle can be drawn through these 4 points.
