Option A is correct. If segment DC bisects segment AB, then point D is equidistant from points A and B because a point on a perpendicular bisector is equidistant from the endpoints of the segment it intersects. This can be obtained using perpendicular bisector theorem.
<h3>What is perpendicular bisector theorem ?</h3>
Perpendicular bisector theorem : In a plane, if we choose a point, say D, on the perpendicular bisector,say PQ, drawn from segment, say AB, then the point D is equidistant from the endpoints, that is A and B, of the segment.
That is, perpendicular bisector PQ of line segment AB is the line with Q = 90° and Q is the midpoint of AB ⇒ AQ = BQ. A point on PQ say D is equidistant from A and B ⇒AD and BD.
Thus in the given question we can use perpendicular bisector theorem.
Here DC is the perpendicular bisector of the line segment AB and therefore AD and BD are equal.
Hence it is clear that Option A is correct.
