Explanation:

Runway hold position markers at runways serve a crucial role in aviation safety. The correct answer to your question is option b: They are used to indicate areas where aircraft should stop before entering or crossing runways for safety purposes. These markings guide pilots during the taxi process to prevent any possible accidents or conflicts with other aircraft that might be taking off or landing. Their presence on the runway indicates to the pilot that they are approaching an active runway and should stop unless they have permission from air traffic control to cross or enter the runway. For example, before takeoff, an aircraft has to taxi from the airport terminal to the runway. In between the terminal and the runway, there are taxiways. The airport uses these markers to indicate stop points for aircraft to hold their positions, ensuring that the runways are clear and safe for the aircraft that is landing or taking off.
