Which of the following is a non-volatile storage medium?

Explanation:
Non-volatile storage keeps data even when power is removed. An SSD uses flash memory to store data persistently, so it remains after you shut down. The other options are volatile memory: DRAM stores data in capacitors and needs constant refreshing; SRAM relies on flip-flops and also loses data when power is cut. The cache is typically a fast volatile memory (often SRAM) used by the CPU to speed up access and it too loses its contents without power. So SSD is the non-volatile choice.
