Detailed explanation-1: -DNA ligase is the enzyme that binds adjacent Okazaki fragments on the lagging strand, resulting in a continuous daughter strand where DNA polymerase had worked in a discontinuous fashion.

Detailed explanation-2: -There is compelling evidence that DNA ligase I is predominantly responsible for joining Okazaki fragments generated by discontinuous DNA synthesis on the lagging strand at the replication fork.

Detailed explanation-3: -Okazaki segments are joined by DNA ligase.

Detailed explanation-4: -Enzyme ligase connects (ligates) the two Okazaki fragments into one continuous newly synthesized complementary strand. DNA ligase I-DNA ligase I connects the Okazaki fragments during the synthesis. Hence, the correct option is option C, ‘Ligase’.
