Which one of the following is the most appropriate reason for aircraft being equipped with conducting tyres?

Aircraft accumulate significant static electricity during flight primarily due to the friction between the airframe and environmental particles like air, dust, and ice [1]. This phenomenon, often called triboelectric charging, can build up potentials of several thousand volts, posing risks such as interference with avionics, damage to sensitive electronic components, and potential ignition of fuel vapors. To mitigate these hazards, modern aircraft tires are manufactured with conductive rubber compounds. These conducting tires allow the accumulated static charge to be safely transferred or 'earthed' to the ground immediately upon landing. Historically, before conductive tires were standard, aircraft used flexible conductive strips to achieve this discharge. While tires also experience friction during the takeoff roll, the primary safety requirement for conductivity is to dissipate the massive static buildup acquired during flight operations [1].
