Mutations are relatively uncommon because

a.frameshift mutations occur very frequently.

b.DNA is able to repair itself over time.

c.physical mutagens such as X-rays seldom damage DNA.

d.DNA repair enzymes often repair errors.

e.transposons are constantly moving throughout the genome.

I believe it's D .DNA repair enzymes often repair errors.

I believe this because enzymes remove incorrect bases with a few surrounding bases, which are replaced with the correct bases with the help of a DNA polymerase and the template DNA. When replication mistakes are not corrected, then it may result in mutations, which sometimes can have serious consequences.
