The situation you've described, where the distribution narrows after selection, indicates that individuals with traits closer to the average are favored, while those with extreme traits are selected against. This is characteristic of **stabilizing selection**.
In stabilizing selection, the range of variation in traits is reduced, resulting in a more concentrated population around the mean.
So, the correct answer is **Stabilizing**.
