Explanation

Category 6A is the minimum cable standard required to support both 10GBaseT at the full 100-meter channel distance and HDBaseT, as both technologies were designed around the Cat 6A specification for reliable operation. Category 5e is eliminated immediately because it tops out at 1 Gigabit Ethernet and cannot handle 10G signaling at all. Category 6 can technically carry 10GBaseT signals, but only up to roughly 55 meters due to alien crosstalk limitations, making it non-compliant for a full 100-meter run and therefore not a valid minimum solution. Category 7 would work, but it exceeds the minimum requirement and carries higher cost, violating the "minimum compliant" constraint in the question.

Memory tip: Pair "6A" with "10G at 100m" - Cat 6A was engineered specifically to solve the alien crosstalk problem that prevents Cat 6 from running 10G the full distance. Any time you see 10GBaseT or HDBaseT and a budget constraint, Cat 6A is the floor, not the ceiling.
