please select the best answer from the choices provided.

a
b
c
d

Explanation:

• Option A: Susan (distance runner) has muscular endurance (repeated contractions over time), not the focus of muscular strength here. Eliminate A.
• Option B: Sprinters (Laura) need muscles to produce high force for short, single - event sprints. Muscular strength is about force production for a single event. This matches.
• Option C: Muscles remaining contracted over long time is endurance, not strength, and sprinters don't have this as a strength - related trait. Eliminate C.
• Option D: Distance running relies on endurance (muscles working for distance), not great force production for strength. Eliminate D.

Answer:

B. Laura because her muscles can produce more force for a single event.
