An industrial sector customer has requested an IBM System x3755 for a high performance computing application. Pricing is the most sensitive decision factor for this customer. They are looking for an entry-level storage solution because the application needs to access about 12 TB of data， with an expected future growth of 10-15 percent. As this is the only server accessing this amount of data， the customer does not want to have a SAN. 
What should the System x Sales Specialist recommend？ （）

A.IBM Memory is tested and supported in IBM systems， plus it automatically assumes the balance of system warranty. It is much more difficult to sell memory upgrades to customers after the server has been purchased.
B.IBM memory is no different to third party memory， so memory can be sold at any time after the sale with ease.
C.IBM memory needs a ServicePac to be sold for warranty to be implemented， so can only be sold at time of system sale.
D.You should sell IBM memory at the time of system sale， as Servers can not be expanded once configured in SSCT.
