Explanation:

Question 4

To identify the roots in "erythroderma", we analyze the word parts. "Erythro" is a root meaning "red" (from Greek, e.g., erythrocyte is a red blood cell), and "derma" means "skin". Option 3 correctly defines "erythro" as red and "derma" as skin. Other options misdefine "erythro" (black, blue, white, yellow are incorrect meanings for "erythro").

We define each term: Erosion is skin loss, excoriation is a scratch, fissure is a crack, macule is a flat spot, bulla is a blister. A crack in the skin is a fissure, so option 3 is correct.

Answer:

1. erythro (red) + derma (skin)
