- D.
Both Cost and Speed of operation
Memory management
Explanation
The correct answer is (b) Memory management.
Conceptual Breakdown
ROM (Read-Only Memory): Standard ROM is "masked" during the manufacturing process. The data is physically built into the circuitry at the factory. This makes it extremely cheap to produce in massive quantities but offers zero flexibility—the user cannot change the data.
PROM (Programmable Read-Only Memory): PROM is purchased as a blank chip. It allows the user (or manufacturer) to program the data once using a special device called a PROM programmer.
