What is the holding speed at MHA of 6000 feet?

The holding speed at a Minimum Holding Altitude (MHA) of 6000 feet is correctly identified as 200 knots. This is based on standardized holding speeds set by aviation regulations which dictate that the maximum speed for holding patterns at altitudes below 14,000 feet is 200 knots.

At altitudes of 6000 feet, aircraft are required to adhere to this limit to ensure safe separation and efficient handling of air traffic in holding patterns. Other choices, while they might be applicable at higher altitudes or in different contexts, do not conform to the regulations governing holding speeds at this specific altitude. Adhering to these speeds is crucial for both safety and standardization in air traffic management.
