Answer: (A)

Verified step by step guidance

1. Understand the question: The problem is asking about the classification of erythema, jaundice, and cyanosis within the context of the integumentary system. These terms describe changes in skin color, so focus on disorders related to skin color abnormalities.
2. Define the terms: Erythema refers to redness of the skin caused by increased blood flow to the capillaries. Jaundice is a yellowing of the skin due to elevated bilirubin levels, often linked to liver dysfunction. Cyanosis is a bluish discoloration of the skin caused by insufficient oxygen in the blood.
3. Relate the terms to the integumentary system: The integumentary system includes the skin, hair, nails, and associated glands. Since erythema, jaundice, and cyanosis all involve changes in skin color, they are categorized as skin color abnormalities.
4. Eliminate incorrect options: Sweat gland disorders, hair follicle infections, and nail deformities do not describe changes in skin color. These options are unrelated to the conditions mentioned in the question.
5. Conclude the classification: Based on the definitions and the focus on skin color changes, the correct classification for erythema, jaundice, and cyanosis is 'Skin color abnormalities.'
