The correct answer is A. Isometric.
An isometric contraction is a type of muscle contraction where the muscle tenses up without changing its length or causing joint movement. This is different from dynamic contractions, where the muscle length changes and movement occurs. In an isometric exercise, the muscle remains static, which can help build strength and stability.
