Video Summary

To determine which diagram represents the gray part of a 3x3x3 cube composed of white, gray, and black cubes, the process involves eliminating incorrect options by comparing placements. Diagram A has an incorrectly placed gray cube, rendering it incorrect. Diagram D also incorrectly positions a cube. Option B features an extra cube that doesn't align with the expected zigzag pattern. Diagram C is missing a cube, making it incorrect as well. Therefore, the correct diagram that illustrates the gray portion accurately aligns with the original structure, and this option is diagram E.
