Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following best illustrates natural selection?
A
An organism with favorable genetic variations will tend to survive and breed successfully.
B
A population monopolizes all of the resources in its habitat, forcing other species to migrate.
C
A community whose members work together utilizing all existing resources and migratory routes.
D
The largest organisms in a species receive the only breeding opportunities.
Explanation: 

Detailed explanation-1: -* The largest organisms in a species receive the only breeding opportunities. An organism with favorable genetic variations will tend to survive and breed successfully. A population monopolizes all of the resources in its habitat, forcing other species to migrate.

Detailed explanation-2: -So, the correct answer is ‘Individuals with the most favorable traits survive and reproduce’

Detailed explanation-3: -Natural selection requires variation between individuals. Mutations and sexual reproduction increase genetic variation in a population.

Detailed explanation-4: -Therefore, the correct option is B. Individuals within a population exhibit genetic variation and those that are best adapted to their environment will survive.

Detailed explanation-5: -Which example best illustrates a condition necessary for natural selection to occur? Cheetahs have nearly identical genetic makeup.
