Which of the following statements is TRUE?

ROM loses information when the computer is powered off.

ROM is Read-Only Memory that cannot be written to after manufacture. It is preprogrammed with permanent instructions. Option A is false because ROM retains data without power. Option B is false because ROM is soldered or built-in, not plugged in like RAM.
ROM (Read-Only Memory) is preprogrammed at manufacture time and is designed so it cannot be rewritten during normal computer operation, which is why it's used to store firmware like the BIOS that must persist unchanged. This is the opposite of RAM, which loses its contents when power is removed — a property incorrectly attributed to ROM in one of the wrong options.
