How does a headwind affect the published accelerate-stop distance required (ASDR) and take-off distance required (TODR)?

• A.Wind has no effect on ASDR or TODR — only temperature affects these values
• B.Headwind increases both ASDR and TODR because the aircraft must accelerate against the wind
• C.Headwind reduces TODR but increases ASDR because stopping is harder with wind assistance
• D.Headwind reduces both ASDR and TODR because airspeed is gained before ground roll, shortening the run to V1 and VR
