Which of the following statements is true?

A) Social facilitation occurs when people perform coaction tasks,but not audience tasks.
B) Social facilitation becomes more likely when the task requires dominant responses.
C) Social facilitation occurs for physical tasks,but not for mental tasks.
D) Humans are the only species to show social facilitation effects.

Social facilitation is more likely to occur when the task involves dominant responses, which are actions that are automatic or well-learned. Tasks that require higher levels of cognitive processing or decision-making may not show social facilitation effects. Option A is incorrect because social facilitation can occur for both coaction tasks (performing a task alongside others) and audience tasks (performing a task in front of others). Option C is incorrect because social facilitation can occur for both physical and mental tasks. Option D is incorrect because social facilitation effects have been observed in other animals as well.
