If $C$ and $D$ are two events such that $C \subset D$ and $P\left( D \right) \ne 0,$ then the correct statement among the following is :
$P\left( {{C \over D}} \right)$$ \ge P\left( C \right)$
$P\left( {{C \over D}} \right)$$ < P\left( C \right)$
$P\left( {{C \over D}} \right)$$ = {{P\left( D \right)} \over {P\left( C \right)}}$
$P\left( {{C \over D}} \right)$$ = P\left( C \right)$
