The correct answer is A. kind.
The word “kind” means “having or showing a friendly, generous, and considerate nature.” This is the best description of the woman in the story, as she is sitting alone at the party and looks sad. It is likely that she is feeling lonely or left out, and the reader can infer that she is a kind person because she is not trying to ruin the party for others by making a scene.
The other options are not as accurate descriptions of the woman in the story. The word “loving” means “having or showing a deep affection or fondness for another.” This does not seem to be the case for the woman in the story, as she is sitting alone and does not seem to be interacting with anyone. The word “mild” means “not severe or intense.” This could be a possible description of the woman, as she is not making a scene or causing any trouble. However, it is more likely that she is feeling sad or lonely, and the word “kind” is a better description of her emotions. The word “cheerful” means “having or showing a happy and lively mood.” This is definitely not the case for the woman in the story, as she is sitting alone and looks sad.
