Explanation

204 pins is the definitive identifier for a DDR3 SO-DIMM (Small Outline Dual Inline Memory Module). SO-DIMMs are the compact form factor used in laptops, small form factor PCs, and some all-in-one systems. Pin counts differentiate memory types: standard DDR DIMMs have 184 pins, DDR2 DIMMs have 240 pins, DDR3 DIMMs have 240 pins, and SDRAM DIMMs have 168 pins. The SO-DIMM variants have different counts - DDR/DDR2 SO-DIMMs have 200 pins, DDR3 SO-DIMMs have 204 pins, and DDR4 SO-DIMMs have 260 pins. The 204-pin count uniquely identifies the DDR3 SO-DIMM form factor, making E the correct answer regardless of the specific DDR generation.
