A leading strand is

a
chain of DNA which is continuously formed.
b
formation of chain which polymerises in 3’ to 5’ direction.
c
chain of DNA which is discontinuously formed.
d
chain of DNA contains Okazaki fragments.

detailed solution

Correct option is A

Leading strand has the polarity 3' → 5' and therefore the replication is continuous on it because DNA-dependent DNA polymerases catalyse polymerisation only in one direction, that is 5' → 3' .
