Final answer:
Zone defense is a basketball strategy where each player covers a specific area of the court and is responsible for any opponent entering that area, unlike man-to-man defense.
Step-by-step explanation:
The name of the defense strategy in basketball where each player is responsible for guarding a specific area of the court is called the zone defense. In a zone defense, players do not cover specific opponents; instead, they guard an area and are responsible for any offensive player who enters that space. This is different from man-to-man defense, where each defensive player is responsible for covering a specific opponent.
