Answer:
C. She was so engrossed in her fantasy world of exotic holidays and luxurious penthouses, that when one of the participants nudged her, she realized that this was the last call for her to go on stage.
Step-by-step explanation:
Daydreaming is the act of getting lost in thought as a result of the reflection of unrealistic things. This situation is usually the lost in thought even though the person is physically present with you.
In the case of Sylvie, as a result of her not being aware that she had been called to go on stage, shows that she was lost in her fantasy world-daydreaming. If not for the other participant nudging her, she would have been disqualified as a result of that call being the last.
