Answer 2

Answer:

The correct statement is that some of the individuals are more predisposed to developing cancer when exposed to mutagens.

Explanation:

A single change or alternation or multiple variations within the genome of the living species is termed as a mutation, and the agent, which results in mutation is known as a mutagen. The products of tobacco are considered as mutagens. It is witnessed that some of the individuals who smoke develop cancer, while some do not. It is generally because some of the individuals are more predisposed to developing cancer when getting exposed to mutagens.  

When an individual is more likely to develop cancer in his or her entire life because of certain genetic and other factors is termed as cancer predisposition. A genetic susceptibility also known as a genetic predisposition can be illustrated as the likelihood of developing a specific disease based on the individual's genetic makeup.  

The individuals who develop cancer generally have family members who exhibited certain kinds of cancer and thus they have greater chances of getting the disease too. This is the reason that the predisposed individuals to cancer have a greater chance of developing cancer when they encounter mutagens and this is the prime reason to illustrate the fact that some of the users develop cancer, while others do not.
