The option that is least likely to cause a species to become extinct due to changes in the environment is "more genetic variation within the species".

Here's why:

1. Genetic variation is crucial for the survival of a species. It allows for a population to adapt to changing environments. With more genetic variation, there is a higher chance that some individuals within the species will have the traits necessary to survive under new conditions.

2. Less genetic variation within a species can be a disadvantage because it means that the species may not have the necessary traits to adapt to changes in the environment.

3. Specific food preferences can lead to extinction if the particular food source becomes scarce or disappears due to environmental changes.

4. More competition for food can also lead to extinction, especially if the food source becomes scarce.

Therefore, more genetic variation within a species is the least likely to cause a species to become extinct due to changes in the environment.
