Solution

The correct option is B Mutations

A transformation is an adjustment in DNA, the inherited material of life. A creature's DNA influences what it looks like, how it carries on, and its physiology. So an adjustment in a living being's DNA can cause changes in all parts of its life. Changes are basic to advancement; they are the crude material of hereditary variety.

So, the correct option is 'Mutations'.
