First xperiment performed by Mendel was related to height of pea plant. Pea plant has two types of height, that is tall plant and dwarf plant. Genotype for tall plant was TT and genotype for dwarf plant was tt.

The right option is Intolerance
Drug Intolerance is a situation
in which drugs cause adverse effects such as drowsiness or stomach upset and
the body is unable to tolerate or bear these effects. An individual with drug
intolerance may be able to continue with the drugs if the dose is reduced
because drug intolerance sometimes disappears as drug therapy continues.
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.
