Answer:

Both physical and chemical factors

Explanation:

A mutation is any alteration in the DNA sequence of the genome of a particular cell/organism. Depending on the type and localization, a mutation can be neutral, deleterious, or even beneficial for the individual that possesses it. Moreover, the mutation rate refers to the probability for a mutation to appear in a cell/organism. Exposure to physical environmental factors (e.g. ultraviolet radiation, X-rays, gamma rays, etc) and chemical factors (e.g., bromine) can increase this likelihood.
