Stretches should be held for approximately 10 seconds. Which type of stretching is this referring to?

The correct answer is A. Active.

Active stretching involves holding a stretch for a period of time, typically around 10 to 30 seconds, while using your muscles to maintain the position. This helps improve flexibility and is generally safe when done properly. Ballistic stretching, on the other hand, involves bouncing movements and dynamic stretching focuses on movement patterns rather than holding positions.
