Hello @jingjingxiao11111@gmail.com,

The support for answer choice B comes from the following pieces of information:

1. Pollination causes a chemical to release into the flower.
2. This chemical causes the flower to wilt within 2 days.
3. Cutting the flower releases the same chemical.

The same chemical is released when the flower is cut. So, what result should we expect? We should expect it to wilt within 2 days. The chemical in question causes wilting, and there is nothing to suggest that nutrients will prevent this.

Note that nutrients are included in the stimulus only when the chemical in question is not released.
