Question

what is the primary responsibility of air traffic control? handling tickets and pricing safely directing planes during their takeoff and landing building and repairing airplanes

Explanation:

Air traffic control's main role is to manage aircraft movements for safety. Handling tickets/pricing is for airline staff, and building/repairing planes is for aviation maintenance. So the correct option relates to directing planes safely during takeoff and landing.

Answer:

B. safely directing planes during their takeoff and landing (assuming the second option is labeled B; if the original labels are different, adjust the identifier but keep the text. Since the options are presented with the second one as "safely directing planes during their takeoff and landing", that's the correct choice for air traffic control's primary responsibility.)
