C Correct answer
Explanation

DRAM (Dynamic Random Access Memory) cells consist of exactly one MOSFET transistor and one capacitor, which stores the electrical charge representing a bit. SRAM uses flip-flops made from multiple transistors (typically 6), while ROM is pre-programmed during manufacturing and doesn't use this simple cell structure. DROM is not a standard memory type.
