Video Summary

To solve the problem of determining the color of a marked part on an octahedron's net, we must understand the labeling and color distribution rules. The octahedron's vertices are marked as pairs of opposites, like A and A', B and B', and C and C'. According to the problem, parts emanating from the same or opposite vertices share the same color. Since the part adjacent to the marked spot, close to A', is light gray at vertex A, the part at A' should also be light gray. Therefore, the marked part should be colored light gray, answering C.
