service best meets your needs?

C. IaaS

D. XaaS

A. Platform as a Service (PaaS) offers developers an inexpensive
method by which they can develop and test their applications.

B is incorrect because Software as a Service (SaaS) delivers end-
user software over the Internet. C is incorrect because Infrastructure as
a Service (Iaas) allows administrators to use cloud servers, storage,

Service (XaaS) is a generic term and PaaS is specific to the stated
need.
