Coarse hair texture is typically characterized by the largest diameter and greatest amount of melanin. This means that coarse hair is thicker and darker in color compared to other hair types. This is why option B, which suggests a balance of melanin, is incorrect as coarse hair usually has higher levels of melanin. Additionally, option C is incorrect as it suggests the smallest diameter and least amount of melanin, which is more commonly found in individuals with fine hair texture. Lastly, option D, which suggests moderate diameter and moderate amount of melanin, does not accurately define coarse hair texture as it has the largest diameter and greatest amount of melanin.
