b. DDR3 and DDR2 both use 240-pin connectors.

d. All these options are correct.
B. DDR3 and DDR2 both use 240-pin connectors is the only correct answer. Although DDR3 and DDR2 both use 240-pin connectors, the connectors use different pinouts and are keyed differently to avoid installing DDR3 in a DDR2 slot or vice versa. DDR3 uses lower voltage than DDR2 . DDR3 memory uses 1.5V DC power, compared to 1.8V DC for DDR2.
