Among the main control system types used, which one is listed alongside pneumatic, electronic, and fluidic?

• A. Mechanical
• B. Hydraulic
• C. Electric
• D. Digital

Answer: (C)

The question is about the major families of control systems based on how energy is used to perform control actions. Pneumatic, electronic, and fluidic are three well-known categories. The category that’s commonly listed with them as a primary control-system type is electric (electrical) control. Electric control systems use electrical energy to power actuators, sensors, and controllers, and they’re a fundamental way to implement precise and fast control, often paired with pneumatic and fluidic approaches in standard classifications. The other options aren’t typically grouped in the same classic set as these three in most curricula; mechanical is more of an older or separate category, hydraulic is a strong candidate but is usually discussed alongside pneumatic and fluidic, and digital refers more to processing methods than a standalone energy-based control family.
