During DNA Replication,synthesis of the Leading Strand of DNA Differs

During DNA replication,synthesis of the leading strand of DNA differs from the synthesis of the lagging strand in that ________.

A) the leading strand is synthesized continuously toward the replication fork,whereas the lagging strand extends away from the fork and is synthesized in short segments called Okazaki fragments
B) the leading strand is synthesized away from the fork and is made in short segments called Okazaki fragments whereas the lagging strand extends continuously toward the replication fork
C) the leading strand is made in the 5'-3' direction by DNA polymerase III,whereas the lagging strand is synthesized in the opposite direction,3'-5'
D) only the lagging strand requires a primer for each of the Okazaki fragments; the leading strand does not require a primer to begin synthesis of the daughter strand
