Correct answer: D
Correct false statements: The false statements are: "The processor has direct access to both primary and secondary memory" and "Memory system is implemented on a single level memory".
The statement that the processor has direct access to both primary and secondary memory is false. The processor can directly access primary memory (RAM), but access to secondary storage (such as disks) involves I/O operations, device controllers, and often DMA—so it is not direct CPU access in the same sense.
The statement that the memory system is implemented on a single level is false. Real systems use a memory hierarchy (registers, caches, main memory, secondary storage) to balance speed, cost, and capacity.
Therefore, the correct answer is the choice that identifies these two statements as false.
