Why each option

Before upgrading laptop RAM, a technician must verify the motherboard specifications to confirm compatible RAM type, speed, form factor, and maximum supported capacity.

AThe speed of the FSB

The Front Side Bus (FSB) speed is largely an older concept and is not the primary factor for determining RAM upgrade compatibility in modern laptops.

BThe motherboard specificationsCorrect

The motherboard (system board) dictates what RAM is compatible - including DDR generation (DDR3, DDR4), maximum speed (MHz), form factor (SO-DIMM for laptops), and total capacity ceiling. Installing incompatible RAM can result in the system failing to POST or running at degraded speeds. Checking the motherboard specs before purchase prevents wasted effort and potential hardware damage from incompatible modules.

CThe BIOS manufacturer

The BIOS manufacturer does not determine RAM compatibility; the chipset and motherboard specifications do.

DThe operating system version

The operating system version does not determine hardware RAM compatibility; the motherboard and chipset do.
