Enzyme that helps in attaching two piece of DNA is in recombinant DNA technology?

Correct option is C

DNA ligase acts on the cut DNA molecules and joins their end, thus making a new combination of DNA molecules. It is a basic class of enzyme that is necessary for all entities to sustain the structural integrity of the genome. The enzyme is very helpful in joining the Okazaki segments that take the shape on the lagging strand when the DNA replicates.
