Correct answer: B
CONCEPT
Computer memory is classified by whether it retains data without power and by how the processor can access it.
RAM is read/write working memory used for active programs and data, whereas ROM is non-volatile memory that retains firmware such as the BIOS.
APPLICATION
Statement A is false: ROM stands for Read-Only Memory, not Real optical memory.
Statement B is true: instructions currently being executed can be held in RAM.
Statement C is true: ROM or other non-volatile firmware storage retains the BIOS.
Statement D is true: RAM supports both reading and writing during normal operation.
Statement E is false: RAM normally loses its contents without power, but ROM retains its stored data.
CROSS-CHECK
The volatility test separates the two memories: active RAM contents disappear after power-off, while the firmware stored in ROM remains available for the next startup.
Therefore, the true statements are B, C and D only.
