Correct answer: A
Concept
Volatility tells us whether stored data survives when power is removed, while storage capacity tells us how much data a device can hold. In the standard memory classification, RAM and ROM are primary memory; secondary memory is non-volatile auxiliary storage, such as an HDD or SSD, outside primary memory.
Application
For statement i, RAM requires continuous power to retain its contents, so it is volatile. Its capacity is also limited relative to mass-storage devices such as HDDs and SSDs. Therefore, statement i is true.
For statement ii, secondary memory means auxiliary storage outside primary memory. Because RAM and ROM belong to primary memory in this classification, statement ii is true.
Cross-check and contrast
ROM is non-volatile, but it is still classified as primary memory; persistence alone does not make it secondary memory.
Cache is high-speed memory close to the CPU and is not secondary storage. This is why statement ii is framed in terms of primary memory rather than every device other than RAM and ROM.
HDDs and SSDs are standard examples of secondary memory because they provide persistent auxiliary storage.
Result
Both statement i and statement ii are true.
