The correct answer is option B. "Their leaves will grow more quickly".
Explanation:
Plants utilize photosynthesis as its main process to obtain energy. In the photosynthesis plants synthesize glucose from carbon dioxide using sunlight and water. In this case, the flower bulbs located in the warm and heated room will have their leaves growing faster than the blower bulbs located in the refrigerator. It has been proved that plants stimulate its photosynthetic processes in moderate warm temperatures, which would result in the plants having more energy and growing their leaves faster.
