Which of the following best describes the storage nature of ROM?

The nature of ROM (Read-Only Memory) is most accurately described as non-volatile and capable of permanently storing data. This means that the data stored in ROM remains intact even when the power is turned off, making it reliable for storing firmware or essential system instructions that need to be readily available when the computer is powered on.

ROM is designed for permanent storage, meaning that once data is written to it during the manufacturing process, it generally cannot be modified or erased by normal means. This characteristic is crucial for the operation of systems that depend on unchanging instructions, such as boot processes.

In contrast, options that refer to temporary storage or volatility do not accurately represent ROM's characteristics. This distinction is vital in understanding how ROM complements other memory types like RAM (Random Access Memory), which is volatile and used for temporary data storage during active processing. Thus, the correct answer emphasizes the permanence and non-volatile nature of ROM in the context of computer memory.
