A4 only

B1 & 2 only

C3 only ✓ Correct

D3 & 4 only

Correct answer: (C) 3 only

Explanation

Statement 3 is true because RAM can be static, called SRAM, or dynamic, called DRAM.

Statement 1 is false because RAM is volatile, losing its contents when power is off.

Statement 2 is false because RAM has a very fast access time compared with other storage.

Statement 4 is false because the BIOS is held in ROM, not in RAM.

SRAM uses flip-flops and is fast, while DRAM uses capacitors needing periodic refresh.

RAM serves as the computer's main working memory for running programs.
