Explanation:

1. Directional selection favors one extreme phenotype in a population, so the first statement is true.
2. Stabilizing selection favors the intermediate phenotype, not all phenotypes equally, so the second statement is false.
3. Disruptive selection favors both extreme phenotypes, so the third statement is true.
4. Stabilizing selection is most common in stable environments, not directional selection, so the fourth statement is false.

Answer:

• First statement: True
