Step 1: Understanding the Question:
• This vocabulary question requires us to identify the exact antonym (opposite in meaning) of the adjective “Intimidating.”
• We must analyze the definition of the target word and select the option that describes an opposing state or attitude.
Step 2: Detailed Explanation:
• Definition of Intimidating: The word “intimidating” describes something or someone that makes others feel frightened, nervous, overwhelmed, or lacking in confidence. It represents an overbearing, menacing, or unapproachable demeanor.
• Let us evaluate each option to find the correct opposite:
• Option (A) “Authoritative” means commanding, powerful, or self-confident. This is a near-synonym or closely associated trait to intimidating, not an antonym.
• Option (B) “Casual” means relaxed, informal, or unconcerned, which does not directly oppose the fear-inducing quality of intimidating.
• Option (C) “Non-serious” describes a lack of depth or solemnity, which is semantically unrelated to intimidation.
• Option (D) “Friendly” describes someone who is warm, approachable, kind, and supportive. A friendly person makes others feel comfortable and welcomed, which is the direct behavioral and emotional opposite of an intimidating person.
• Therefore, “Friendly” is the most suitable antonym.
Step 3: Final Answer:
The correct option is (D).
