Correct Answer: Option A — control pods

Control pods are retrievable subsea units that house the pilot valves and regulators necessary to translate surface commands into hydraulic actions. These pods manage the high-pressure hydraulic fluid required to operate the blowout preventer stack functions, ensuring reliable control of well-pressure barriers from the surface drilling console.
