Solution

The correct option is A Cut DNA at specific base sequences
The restriction endonucleases are the enzymes which cleave the DNA at specific recognition sites present in the DNA sequences. This helps in the production of fragments and desired genes. This enzyme is widely used with respect to the recombinant DNA technology.
Thus, the correct answer is option A.
