Due to the pricing of MP processors， a customer is evaluating DP processors. They have current budget constraints and do not want to discard obsolete hardware after a scaling step. It is calculated that two processors will meet their immediate needs. Their projected growth indicates they will need more than four processors. Which of the following recommendations will provide the best path for growth at the lowest cost？（）

A.Begin with a dual DP x445 and scale in the same chassis
B.Begin with a dual MP x445 and scale in the same chassis
C.Begin with a dual DP x445 and scale out in an extra chassis
D.Begin with a dual MP x365 and scale to a different machine
