What Is the Difference Between the Leading Strand and the Lagging

What is the difference between the leading strand and the lagging strand in DNA replication?

A) The leading strand is synthesized in the 3′→5′ direction in a discontinuous fashion,while the lagging strand is synthesized in the 5′→3′ direction in a continuous fashion.
B) The leading strand requires an RNA primer,whereas the lagging strand does not.
C) The leading strand is synthesized continuously in the 5′→3′ direction,while the lagging strand is synthesized discontinuously in the 5′→3′ direction.
D) There are different DNA polymerases involved in elongation of the leading strand and the lagging strand.
