The correct answer is option 4- All of the above.

The technique of differential piece rate system was developed by Taylor in order to fulfill all of the above things.

The standard time and other parameters should be determined on the basis of the workstudy. The workers can then be classified as efficient or inefficient on the basis of these standards. He wanted to reward efficient workers. So he introduced different rate of wage payment for those who performed above standard and for those who performed below standard.
