$Assertion :$ In $SHM$, acceleration is always directed towards the mean position.
$Reason :$ In $SHM$, the body has to stop momentary at the extreme position and move back to mean position.

$SHM$ is basically to and fro motion about the mean position. So when the body goes away from mean position an acceleration always try to return the body towards mean position. As the acceleration in $SHM$ is always in opposite phase to that of displacement. The displacement of the particle in $SHM$ at an instant is directed away from the mean position then acceleration at that instant is directed towards the mean position.
