The correct answer is D.
OBJ-3.3: Small Outline Dual Inline Memory Modules (SODIMM) is a small form factor used in memory modules. SODIMM is used in nearly every laptop available. For the exam, if you see a question asking about memory and laptops, the answer will most likely be SODIMM. SODIMM is also heavily used in Micro PCs (like Mac Minis) and all-in-one computers due to their smaller size.
