ANSWER--
Less than 5cm, option c is correct
EXPLANATION--
In rectangle OPQR, the diagonals are congruent:
PR = OQ
If Q is on the circle with center O and radius 5 cm, then OQ = 5cm, hence PR = 5 cm.
If Q lies outside the circle, then OQ > 5 cm and hence PR > 5 cm
If Q lies inside the circle, then OQ < 5 cm, hence PR < 5 cm
