Option A is the right one for this question.
The undergrowth of tropical rainforest most likely requires less sunlight.
The tropical rainforest floor receives only 2% of the sunlight; only plants can grow in this region.
The forest floor is a relatively clear of vegetarian, because of the low sunlight penetration.
Hormones are chemicals made in the soil that affect parts of plants. The statement is false.
<h3>How are gibberellins able to affect other parts of the plant?</h3>
Gibberellins stimulate the growth of shoots which increase the biomass and vegetative growth of plants. If vegetative growth increases, the root biomass is also increases.
So we can conclude that other parts of the plant are also affected due to gibberellin because it stimulates the growth of shoots which is the upper portion of the plant.
