What is static pressure and dynamic pressure, and how do they relate to airspeed indicators?

What is static pressure and dynamic pressure, and how do they relate to airspeed indicators?

• A. Static pressure is ambient pressure; dynamic pressure relates to airspeed; pitot-static system uses both to compute indicated airspeed.
• B. Static pressure is a function of temperature; dynamic pressure is unrelated to airspeed; airspeed is calculated from static pressure alone.
• C. Both static and dynamic pressures are the same; airspeed is derived from total pressure.
• D. Dynamic pressure is ambient pressure; static pressure relates to speed through the atmosphere.
