Solution

The correct option is A restriction endonuclease and ligase
Explanation:

Restriction enzymes are a class of endonucleases that are DNA-cutting enzymes. Each enzyme recognizes one or a few target sequences and cuts DNA at or near those sequences. DNA ligases are DNA-joining enzymes. If two separate pieces of DNA have matching ends, ligase links them to form a single, unbroken molecule of DNA.
