Final answer:

D. Melanin, produced by melanocytes in the skin, is the correct example of an endogenous, nonhematogenous pigment, distinguishing it from Biliverdin, Hemosiderin, and Lipofuscin, which are associated with blood processing or its breakdown products.

Step-by-step explanation:

An example of an endogenous, nonhematogenous pigment is D. Melanin.

This pigment is produced by cells known as melanocytes, which are located in the epidermis's stratum basale.

Melanin is the main pigment responsible for the color of human skin, and unlike the other options provided (A. Biliverdin, B. Hemosiderin, C. Lipofuscin), it is not a breakdown product of hemoglobin nor associated with the processing or failure of blood components.

Biliverdin and Bilirubin are related to the degradation of hemoglobin and are significant in conditions like bruising or jaundice respectively, but they are not categorized as endogenous, nonhematogenous pigments.

Therefore, answer D, Melanin, is the correct choice to this question, as it fulfills the criteria of being endogenous and not derived from the blood.
