A mobile phone has a hypothetical memory that is called as ROM, if this is erasable also it is called as*PROMTROMKROMnone of these

The correct answer to the question is EPROM.

Explanation:

• ROM (Read-Only Memory) is a type of non-volatile memory that is used to store firmware or software that is not intended to be modified frequently.
• An EPROM (Erasable Programmable Read-Only Memory) allows for the data to be erased using ultraviolet light and then reprogrammed, which is the characteristic referred to in the question as "erasable."
• Other options like PROM (Programmable Read-Only Memory) are not erasable once programmed, and TROM (Transistor Read-Only Memory) and KROM (commonly used as a term in certain contexts) do not accurately describe an erasable memory type in this context.

Thus, the best choice reflecting an erasable ROM type is EPROM.
