answer : B. melatonin
This is due to a growth hormone called auxin which has a stimuli (affinity) towards light. Thus the plant responds to the stimuli by leaning towards it.
An organism responds to a stimulus.
The gland in the brain that is regulated by light is the pineal gland. It responds to changes in light exposure, particularly through the production of the hormone melatonin which is involved in regulating the sleep-wake cycle.
The suprachiasmatic nucleus (SCN) in the brain serves to synchronize biorhythms with natural light and dark cycles by receiving visual inputs through the eyes. It plays a crucial role in regulating the body's circadian rhythms, which control the sleep-wake cycle and other physiological processes. Melatonin, a hormone produced by the pineal gland, is also involved in this process as it responds to light cues received by the SCN.
It IS D because it responds to the light.

Light responds differently to different surfaces. Depending on the surface different amounts of the light will be reflected and refracted.
Sun light is not a hormone.It is an energy.
The sun is an example of a natural light source. A source which gives of light that is natural (not made by electricity) is a natural light source.
Orange light at night can disrupt the body's natural sleep-wake cycle by suppressing the production of melatonin, a hormone that helps regulate sleep. This disruption can lead to sleep disturbances and other health issues.
