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 southern exposure (which brings light). Among the options, "glowing" relates to light/brightness, matching the root's likely meaning (Latin "candere" means to shine/glow). "Beautiful", "pleasant", and "condition" don't relate to light/shine.

B. glowing
