Solution
The correct option is D Melanocyte stimulating hormone (MSH)
MSH is important in the regulation of melanin synthesis in cells called melanophores (a type of chromatophore) that are in the skin of amphibians, some fishes, and reptiles. Light reflected from water surface stimulates photoreceptors, which send information to the hypothalamus. Pituitary MSH then causes the pigment synthesis in the melanophores to disperse and the skin to darken.
