Which of the following describes a team format without a handicap system?

A four-person scramble is a team format that does not utilize a handicap system. In this format, each player on the team hits a tee shot, and then the best shot is selected for the next stroke. All players then play their next shots from that chosen location, and this process continues until the ball is holed. The team's overall score is determined by the number of strokes taken to complete the hole, and it is a straightforward approach that encourages teamwork without the complexities introduced by handicaps.

In contrast, the other formats listed often involve elements of individual performance or comparisons against established skill levels through handicaps. For example, individual stroke play is based solely on each golfer's performance, and team match play focuses on head-to-head competition, which can involve different skill levels. The best ball format also typically incorporates individual handicaps to level the playing field among participants. Hence, a four-person scramble is unique in its simplicity and direct approach, making it the correct choice for a team format without a handicap system.
