Option 1 (Embarrassing) -> Both describe situations that cause discomfort or unease.
Option 2 (Comfortable) -> This is the opposite; disconcerting means unsettling, not comfortable.

Option 4 (Adroit) -> This means skillful or clever, not connected to causing unease.
Hence, Option 1: Embarrassing -> "Disconcerting" means causing one to feel unsettled or disturbed. While not a perfect synonym, "embarrassing" is the closest option as it similarly describes something that makes people feel uncomfortable or uneasy -> correct
