Explanation:

The experiment involves two genetically identical bean plants with different light exposure (one in direct sunlight, one in a closet). The independent variable is light, so the hypothesis should relate sunlight to plant height. The fourth option (partially visible but inferred) likely states "The amount of sunlight affects the heights of bean plants," which matches the experimental setup (varying light, same genetics/seed type/temperature assumed constant). Other options: genetic variation is ruled out (identical plants), seed type is same, temperature isn't varied here.

Answer:

The option (likely the fourth, partially shown) with text "The amount of sunlight affects the heights of bean plants" (exact wording based on context: varying light exposure, so this hypothesis is tested). If options are labeled, e.g., D. The amount of sunlight affects the heights of bean plants (assuming the fourth option is D), then the answer is D. The amount of sunlight affects the heights of bean plants.
