What is the primary function of a Goal Attack (GA) in netball?

The primary function of a Goal Attack (GA) is to assist in play outside the shooting circle, making option B the best choice. The GA plays a crucial role in both scoring goals and facilitating the overall flow of the game. They are allowed to enter the attacking half and contribute significantly to the team's offensive strategies by setting up opportunities for the Goal Shooter (GS) and making plays that can draw defenders away, creating space.

This dual responsibility of both scoring and making plays distinguishes the role of the GA. While they do shoot and score goals, this is only part of their function. They often operate beyond the shooting circle, engaging in passing and creating dynamic movement to support their teammates. Their role in orchestrating plays contributes to the team's effectiveness in offense.

Other options suggest a more limited role for the GA, focusing only on shooting, defending, or calling for passes. The GA's involvement in various aspects of attacking play, including working collaboratively with other players, is what makes the answer clear.
