Which of the following scenarios demonstrates the concept of social facilitation?
A Anthony plays soccer very well. College scouts come to see him, but since Anthony does not know they are there, his performance is not impacted by their precense.
B Hannah is a skilled singer, and she performs her best during concerts with large audiences.
C Kiley wears sandals to school because she noticed that most of her friends were wearing them the previous day.
D Savannah is anxious about making a mistake at her new nursing job, and when others are around she sometimes forgets to complete a task.

I think the answer is B but I know social facilitation can also have a negative impact so I feel D could also be a reasonable answer.
