The correct answer is Post Hoc Fallacy
Explanation:
In this situation, the speaker believes the victory of the team is caused by the action of drinking the red power juice simply because drinking this juice occurs before the team wins. This is a fallacy because an event preceding another does not mean one event causes the other. Indeed, it is likely in this case the victories are related to factors such as training, strategy, etc. rather than the red juice. Moreover, this fallacy is formally known as the Post Hoc Fallacy, which is the Latin term for "after this" as one event follows another and this is claimed to be the cause.
