Answer:
A
Explanation:
The condition that is necessary for the natural selection to occur is that each individual organism that is born must survive. The correct option is B.
What is natural selection?Natural selection is the process by which living organism populations adapt and change.
Individuals in a population are naturally variable, which means they differ in some ways. This variation indicates that some people have traits that are better suited to their environment than others.
Natural selection, Darwin proposed, is a mechanism for evolution in which heritable traits that help organisms survive and reproduce become more common in a population over time.
The phrase "survival of the fittest" refers to the process of natural selection, a mechanism that drives evolutionary change.
The condition for natural selection to occur is that each individual organism that is born must survive.
Thus, the correct option is B.
