Which of the following descriptions concerning performance evaluation for a computer system is correct?

a) Since the benchmark program used to measure CPU performance covers a wide range of applications, it can be broadly used from computer installation to system expansion design.
b) When planning to enchance system resources to handle increased load on the computer system, a prototyping model based on anticipated load is not effective.
c) A software monitor and queue model are effective in predicting computer system performance at a stage when the system is not actually running.
d) For systems already in operation, it is possible to find problems regarding performance by collecting information, statistical data and charging data using a software monitor and then analyzing that information.
