Because plants have more nutrients

Post
Because plants have more nutrients when they are exposed to sunlight and water at their roots, the growth of young plants generally increases when there is a decent amount of sunshine. By contrast, however, following a prolonged period of sunny days, the growth of hosta plant leaves is minimal and the outside edges of its leaves begin turning brown, even when rainfall is plentiful.

Which of the following, if true, does most to explain the contrast described above?

(A)During periods of extreme sun, the population of insects that feed on hosta leaves tend to fall.

(B)The more rainfall the hosta plant receives, the more capable it is of conducting photosynthesis and growing its stem and leaves.

(C)When hosta plants reach their mature size, conditions within the soil can become toxic or disadvantageous for nearby plants

(D)Hosta plants completely shutdown their internal functions for short intervals in periods of excessive sunlight.

(E)Except during periods of extreme sunlight, hosta plants tend to thrive better when rainfall is light and occurs steadily than when rainfull is heavy and occurs suddenly.

Can some experts explain the best option?

Here's our scenario: Sunshine usually leads to healthy growth for plants. For hosta, a lot of sunshine leads to minimal growth and some leaf decay.

To summarize, plentiful sunshine is good for most plants and bad for hosta. So we're looking for some negative consequence of excessive sunshine on hosta. That's what we get from D If sunshine can cause the internal function of the hosta to shutdown, this would explain why the plant reacts negatively to excessive sunshine.
