Answer 1

C. SO-DIMM DDR3

Step-by-step explanation:

The SO - DIMM or small outline dual in-line memory module is a RAM memory device used in small computer systems to run active programs.

They are used mostly in laptops and a few other small systems. It is half the size of the DIMM found in desktops. They are variants of the devices and can be identified by the number of pins, and the number and position of the notch on it.

The SO-DIMM DDR and DDR2 have 200 pins, with ddr notch positioned at one fifth the length of the device and the ddr2 notch close to the center.The SO-DIMM DDR3 with 204 pins and DDR4 with 260 pins.
