condition pleasant glowing beautiful

Explanation:

To determine the meaning of the root "cand" in "candescent", we analyze the context. The sentence says the "candescent quality of the room was improved by the southern exposure". Southern exposure typically brings light, so we relate this to the root's meaning. The root "cand" (from Latin "candere") means to glow or shine. Among the options, "glowing" matches this meaning. "Condition" is unrelated, "pleasant" and "beautiful" don't relate to the light - related context suggested by southern exposure improving the room's quality.

Answer:

glowing
