Explanation

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.
