An x445 with two 3.0GHz DP processors and 2GB of RAM is running a processor-intensive floating-point geological application that calculates pressures in the earth’s crust. It takes a long time for each calculation， and the director of computing wants the calculations to take less time. Memory addressed by the application may also be a bottle neck. Which of the following will most improve the ability to run the calculations in less time？（）

A.Replace the two 3.0 GHz DP processors with four 3.0GHz MP processors with a 4MB L3 cache and 4GB of RAM
B.Replace the x445 with an x366 with four 3.66 EM64T processors with a 1MB L2 cache and 4GB of RAM
C.Replace the two 3.0GHz DP processors with two 3.0GHz MP processors with a 4MB L3 cache and 2GB RAM
D.Replace the two 3.0GHz DP processors with four 3.0 GHz DP processors with a 512KB L2 cache and 4GB RAM
