Starting from rest, a body slides down a \( 45^{\circ} \) inclined plane in twice the time it takes to slide down the same distance in the absence of friction. The coefficient of friction between the body and the inclined plane is [CBSE PMT 1990;
Kerala PMT 2006; Similar JIPMER 1999]
(a) \( 0.33 \)
(b) \( 0.25 \)
(c) \( 0.75 \)
(d) \( 0.80 \)
