Muscular strength is defined as the maximum amount of force a muscle or muscle group can generate in a single effort. Option A is related to muscle fiber length changes over time (not strength). Option C describes muscular endurance (repeated movements over time). Option D is about joint range of motion (flexibility). Only option B correctly defines muscular strength.
