A. Low oxygen level: Cyanosis (bluish discoloration) and pallor (pale skin) suggest inadequate oxygenation of the blood, which can be due to respiratory or circulatory issues.

B. Liver disease: Liver disease is more commonly associated with jaundice (yellow discoloration) rather than cyanosis or pallor.

C. Skin cancer: Skin cancer often presents as abnormal moles, sores, or lesions rather than generalized cyanosis or pallor.

D. High blood sugar: High blood sugar (hyperglycemia) does not directly cause cyanosis or pallor; it may lead to dry skin and poor wound healing.

B. Exposure to environmental pollutants: Some pollutants may contribute to skin damage, but UV radiation is the primary cause of skin cancer.

C. History of viral illness: Some viruses, such as HPV, are linked to specific cancers (e.g., cervical cancer), but they are not a primary cause of skin cancer.

D. Sun exposure: UV radiation from the sun is the most significant risk factor for skin cancer, particularly basal cell carcinoma, squamous cell carcinoma, and melanoma.

B. Glucose: Glucose is a carbohydrate used for energy, not for building hormones or hemoglobin.

C. Proteins: Hormones (such as insulin and growth hormone) and hemoglobin (which carries oxygen in red blood cells) are protein-based molecules essential for bodily functions.

D. Carbohydrates: Carbohydrates provide energy but do not contribute to the structure of proteins like hormones and hemoglobin.
