The correct answer is A) RAM is volatile memory and the contents of RAM are lost when the power is removed. RAM is a type of computer memory that is used for temporary storage of data and instructions. It is considered volatile memory because the information stored in RAM is lost when the power to the computer is turned off or interrupted. This is in contrast to non-volatile memory, such as hard drives or solid-state drives, which can retain data even without power. The other options are incorrect because B) and C) are false statements, as RAM is indeed volatile memory, and D) is also false, as the contents of RAM are lost when power is removed, not retained.
