Myoglobin is a protein primarily located in the striated muscle hence it is known as the muscle hemoglobin.

Melanin is the pigment that gives color to hair, skin, and eyes in humans and animals. It has no role in oxygen transport or in muscle hemoglobin function.

This option is correct. Myoglobin is a pigment protein found in muscle tissue of vertebrates, including humans. It has a reddish-brown color and is responsible for storing and transporting oxygen within muscle cells. Myoglobin has a higher oxygen affinity than hemoglobin, making it effective in oxygen storage and release during muscle activity.

Rhodopsin is a light-sensitive pigment located in the rod cells of the retina. It is essential for vision in dim light, allowing the eyes to detect shapes and movement when illumination is low.

Lutein is a yellow pigment belonging to the carotenoid family. It is commonly found in plants and is important for photosynthesis and as an antioxidant in the human diet. It is not associated with muscle hemoglobin.
