Answer:
B. Stabilizing selection.
Explanation:
In a population, natural selection can favor one of the many phenotypes present. Directional selection is the phenomena where one of the extreme phenotypes is favored. Disruptive selection is the phenomena where both the extreme phenotypes are favored over the average phenotype. In stabilizing selection, the extreme phenotypes are not preferred so that maximum organisms fall under the average category.
Here, low spine number cacti are being eaten by peccaries and high spine number cacti are being eaten by a parasite. Both of these extreme phenotypes are under attack which will favor the cacti with average number of spines to survive. Hence, this is an example of stabilizing selection.
