A<em> perpendicular bisector</em> is a straight <u>line</u> drawn at an angle
to a given line segment and <em>divides</em> the segment into two equal parts. Thus the appropriate answer to the question is option B. Definition of the <em>perpendicular</em> bisector.
A <u>bisector</u> is a line that divides a given line segment into two equal parts. It is always drawn at a <em>right angle</em> to the given line segment, thus sometimes referred to as a <em>perpendicular bisector</em>.
So in the given question, line CD divides AB into <u>two</u> equal halves and it is drawn at an angle of
.
Such that;
<AED = <BED (<u>right </u>angle property)
Therefore, segment CD is a <em>perpendicular bisector</em> of segment AB.
Thus the required answer is option B. Definition of the <em>perpendicular bisector</em>.
