Answers
C.
Quad-channel with DDR5 SODIMM
D.
Dual-channel with DDR4 RAM
Answers
D.
Dual-channel with DDR4 RAM
Suggested answer: B

Explanation:

Quad-channel memory architecture allows the CPU to access four memory modules simultaneously, increasing the memory bandwidth and performance. DDR4 RAM is a type of memory that has higher speed and lower power consumption than DDR3. SODIMM is a smaller form factor of memory that is typically used in laptops, not desktops. ECC RAM is a type of memory that can detect and correct errors, but it is more expensive and slower than non-ECC RAM. Triple-channel memory architecture is less common and less efficient than quad-channel.
