Low oxygen level

Liver disease

Skin cancer

Answer and Explanation

The Correct Answer is A

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.

D. Is burned as fuel to get energy: Glucose is the body's primary energy source, metabolized via glycolysis, the Krebs cycle, and oxidative phosphorylation.

E. Is the most important sugar in the body: Glucose is the key monosaccharide required for cellular metabolism and ATP production.
