Muscular strength is defined as the amount of force a muscle can generate. This refers to the maximum amount of weight or resistance that a muscle can move in a single effort. Meanwhile, flexibility (option A) refers to the range of motion in a joint and is not directly related to strength. Endurance (option C) is the ability of a muscle to sustain repeated contractions over a period of time, whereas muscular strength is focused on a single, maximum effort. Lastly, the speed of muscle contraction (option D) is known as muscular power, which is different from strength.
