The 'squat switch' (weight-on-wheels switch) fitted to landing gear legs prevents which ground-damaging events?

• A.Landing gear retraction on the ground, and ground spoiler deployment on the ground
• B.Engine reverse thrust application above 80 kt (prevents structural damage from early reverser deployment)
• C.Cabin pressurisation on the ground (prevents cabin pressurisation while doors are open for boarding)
• D.Nose wheel steering activation in flight (prevents steering commands from deflecting the nose gear in the wheel well)
