What term describes a person who is easy to like and has a pleasant demeanor?

The term that best describes a person who is easy to like and has a pleasant demeanor is "likable." This word refers to an individual's ability to attract friendly sentiments and positive feelings from others. A likable person often possesses traits such as kindness, warmth, and openness, making interactions with them enjoyable. This quality can lead to forming strong relationships, enhancing social dynamics, and creating a welcoming environment.

In contrast, the other terms describe negative attributes. "Displeasing" suggests something that causes dislike or dissatisfaction, "unfriendly" implies a demeanor that is not welcoming or kind, and "unpleasant" indicates a disagreeable or annoying nature. These words highlight qualities that would typically repel rather than attract positive feelings, further underscoring the appropriateness of "likable" as the correct answer.
