Solution

The correct option is B DNA ligase
An enzyme that joins small pieces of DNA is called DNA ligase.
DNA ligase is a specific type of enzyme that facilitates the joining of DNA strands by forming phosphodiester bonds between the two strands.
It plays a role in repairing single-strand breaks.
Thus, the correct answer is option B.
