Answer 2

Answer:

b. stabilizing selection

Explanation:

Stabilizing selection is a from of natural selection that selects against the two extreme ends of a phenotypic trait while favoring the intermediate phenotypes.

Stabilizing selection is the opposite of disruptive or diversifying selection that favors the extreme forms of a trait.

For example, if a plant inhabits an area with low sunlight and high wind speeds, short plants will not be able to compete for sunlight. Whereas, extremely tall plants may receive mechanical damage from the wind speed.
