Solution
The correct option is A Infinite points, between the rays PA and PB To locate points which are equidistant from P and at a distance d, take a compass, with P as center and radius as d, draw an arc which cuts the rays PA and PB at C and D as shown.
Now, all the points on this arc CD are at a distance d from P and, hence, they all meet the given condition.
Therefore, an infinite number of points meeting the given conditions can be marked between PA and PB.
