Ecstasy is one example of which of the following? depressants narcotics club drugs stimulants

Ecstasy, also known as MDMA, is used recreationally, so it can be called a club drug. However, it is illegal in the US, so it would be considered a narcotic as well. The effects it has are also of the stimulant variety, so they would fall under that category as well. It is definitely not a depressant. 

With this information, I would choose Club Drug since it is a pretty broad definition that includes both Stimulants and Narcotics under it's umbrella.
