The correct answer is A. Sexual
Step-by-step explanation:
Sexual selection is a type of natural selection linked to sexual reproduction, this selection occurs because organisms mate with individuals of the same species but opposite biological sex, this also implies in mating organisms look for specific traits. For example, females peacocks look for males with more attractive tails and this leads to natural selection as individuals with more "eyes" on their tails reproduce more. This type of selection also occurs in the case of a female deer that mates with the male deer with the largest antlers, because this shows not only that organism mate with individuals of the opposite biological sex but that reproduction is determined by certain traits and this leads to natural selection.
