C Correct answer
Explanation

Restriction endonucleases are enzymes that cut DNA at or near specific recognition nucleotide sequences known as restriction sites. Type I restriction enzymes cleave at sites remote from recognition site. Type II restriction enzymes cleave within or at short specific distances from recognition site. Type III restriction enzymes cleave at sites a short distance from recognition site.
