A population is better able to respond to environmental change if

A. it contains fewer individuals but high genetic diversity.

B. it contains a large number of individuals but low genetic diversity.

C. it has the ability to provide ecosystem services.

D. it has evolved more recently.

E. it has migrated to its current habitat.

The correct answer is option A. it contains fewer individuals but high genetic diversity.

Explanation:

The population with higher genetic diversity and fewer individuals will respond to highly environmental changes as if a population have higher genetic diversity will tend to adopt more changes as they have a diverse genome. The diverse genome will have the ability to adapt resistance to new diseases.

Thus, the correct answer is option A. it contains fewer individuals but high genetic diversity.
