Answer:
D) Volatile
Explanation:
Volatile memory needs the power to retain the work, and Random Access Memory (RAM) is one of the volatile memory in computers or laptops. If the power cuts, RAM cannot save the data. On the other hand, ROM or Read Only Memory can save the data, for example, hard drive. RAM is not a permanent data storage. It is not stable since it needs power. However, it is an essential element to start the computer. Therefore, option D is correct.
