A particular parallel program computation requires 100 seconds when executed ona single processor. If 40 percent of this computation is "inherently sequential" (i.e.,will not benefit from additional processors), then the theoretically best possibleelapsed times for this program running with 2 and 4 processors, respectively, areA. 20 and 10 secondsB. 30 and 15 secondsC. 50 and 25 secondsD. 70 and 55 secondsE. 80 and 70 seconds.
