B
Ability to lift a heavy weight or exert a lot of force
C
Ability to move your joints through a wide range of motion
D

Explanation: 

Detailed explanation-1: -Muscular strength is the ability to exert maximal force in one single contraction, such as lifting a weight that you could lift only once before needing a short break. Muscular power refers to a great force production over a short period of time, such as in fast leg kicks and explosive jumping.

Detailed explanation-2: -Muscular strength is the ability of the muscle to exert force during an activity (USDHHS, 1996 as adapted from Wilmore & Costill, 1994). The key to making your muscles stronger is working them against resistance, whether that be from weights or gravity.

Detailed explanation-3: -Muscular strength is determined by how much force you can exert or how much weight you can lift. Building muscular strength uses heavier weights for fewer repetitions. Muscular endurance refers to the ability of a muscle to sustain repeated contractions against resistance for an extended period of time.
