How Does CRISPR Allow for Precise Modification of Genetic Material

How does CRISPR allow for precise modification of genetic material?

A) The enzyme used to cut the DNA matches up with a specific gene sequence where the cut is to be made.
B) One enzyme cuts out specific genes and another enzyme inserts these genes in different places in the DNA.
C) A proofreading enzyme replaces incorrect nucleotide sequences in defective genes with the correct sequences.
D) An enzyme cuts the DNA at random locations and inserts a specific genetic sequence at each break in the DNA.
E) An enzyme copies the nucleotide sequence of a specific gene and inserts the copy into the DNA strand.
