(Note: The Homework #3 problems are created based on Problem 18 of Chapter 3.) For the mentioned computation X = (A-(BC)) x (D+E * F) which will be implemented using different microprocessors running different instruction formats, in an order of Microprocessor 0, Microprocessor 1, Microprocessor 2 and Microprocessor 3, which of the following sets of the Total Time (in ns) taken to perform the computation is more likely correct? (a) 420, 500, 550, 560; (b) 400, 420, 440, 460; (c) 420, 550, 560, 500 (d) 500, 490, 480, 470
