Given below are two statements :
Statement $I:$
DNA polymerases catalyse polymerisation only in one direction, that is $5^{\prime} \rightarrow 3^{\prime}$
Statement $II:$
During replication of $DNA$, on one strand the replication is continuous while on other strand it is discontinuous.
In the light of the above statements, choose the correct answer from the options given below :
