A student attempts to slide a block down a smooth, dry ramp as shown, but the block does not move. The most likely explanation is that:
a. the ramp is not steep enough for gravity to have any effect.
b. there is no normal force between the block and ramp.
c. the coefficient of dry sliding friction is too small to allow the block to slide.
d. the coefficient of static friction is too large to allow the block to slide.
