Answer:
The correct option is A.
Step-by-step explanation:
Intraspecific competition refers to the type of competition in which living organisms belonging to the same specie compete for common limited resources. When the required resources that are needed to survive become scarce, then it is only the fittest organisms that will survive, these set of organisms usually found a way of adapting to the changes that occur in their environments and they usually go on to reproduce young ones that replace them. This process leads to evolution in which living organisms that possess the right traits are able to survive and reproduce in a particular habitat.
