A. Bilirubin: Bilirubin is a yellow pigment derived from the breakdown of red blood cells, associated with jaundice rather than freckles or moles.

B. Carotene: Carotene is an orange pigment found in foods like carrots and can contribute to skin tone but is not the main factor in moles or vitiligo.

C. Keratin: Keratin is a structural protein found in skin, hair, and nails but does not influence pigmentation.

D. Melanin: Melanin is the pigment responsible for skin color, moles, freckles, and conditions like vitiligo, which causes depigmentation.

A. It is due to too much glucose in the cells: Diabetes is characterized by high blood glucose levels due to impaired insulin action, not excessive glucose within the cells.

B. Very few people have the disease: Diabetes is a common chronic disease, affecting millions worldwide.

C. Lifestyle choices (diet and exercise) have no effect on it: Lifestyle choices significantly impact diabetes management, particularly for Type 2 DM, where diet and exercise help control blood sugar levels.

D. It is related to abnormal insulin production and/or impaired insulin utilization: Diabetes Mellitus occurs due to either inadequate insulin production (Type 1 DM) or insulin resistance (Type 2 DM), leading to hyperglycemia.
