The correct answer to this question is C, Spontaneous Mutations. A cause of spontaneous mutations is when deamination occurs of the cytosine to uracil. This occurs in the double helix. These mutations are rare and occurs on only one in one million cells. The rates of spontaneous mutations are 0.1-100 per genome.

This rate is higher in eukaryotes cells. There are many types of spontaneous mutations, with the most being base substitutions. Mutations can. E both recessive and dominant. Another type of mutation is induced mutation It comes when environmental agents that influence create mutagents. This affects the structure of the DNA.
