C. Strength is improved by lifting the heaviest weight possible and because the weight is so heavy the number of repetitions must be low. This will cause adaptions in the muscle fiber that make lifting heavier weights possible.
To get stronger means to improve and increase the muscle strength, which is the ability to exert a maximal amount of force for a short period of time. To get stronger, you should use a few repetitions with maximum weight. Lifting heavy weights increases the overall maximum strength and greatly improves the ability to lift heavier weights.
