Final answer:
A goal scored by a team that's playing with fewer players due to a penalty is called a Short-Handed Goal. The team is considered 'short-handed' because they have fewer players on the ice.
Step-by-step explanation:
When a team has a player in the penalty box and is playing with fewer players than their opponents on the ice, and that team scores a goal, it is called a Short-Handed Goal. Conversely, when the opposing team, which has more players on the ice due to the penalty, scores a goal, that is called a Power Play Goal. A Overtime Goal is any goal scored during the overtime period, and a Hat-Trick Goal is a term used when a single player scores three goals in one game; neither of these terms are relevant to the situation described. The answer to the provided question is B) Short-Handed Goal.
