A) Mutations in genes that control cell growth and division
B) Mutations in genes that control pigmentation in skin
C) Mutations in genes that control the differentiation of cell types
D) All of these are correct.
E) None of these are correct.

Accepted Answer

Mutations in genes that control cell growth and division are the primary cause of cancer. Mutations in pigmentation genes or genes controlling differentiation of cell types may lead to disorders related to skin or other tissues, but they do not directly cause cancer. Therefore, options B and C are incorrect. Option D is incorrect because only option A is true.
