Correct answer: B
Primary memory refers to the volatile memory directly accessible by the CPU, such as RAM (DRAM, SRAM) and ROM variants (PROM). These are used for temporary data storage during processing.
Secondary memory, like HDD (Hard Disk Drive), is non-volatile and used for long-term data storage. It is not directly accessible by the CPU and is not considered primary memory.
Therefore, HDD is not a type of primary memory, making it the correct choice for the question.
