Here’s an explanation: During unaccelerated flight the forces along the aircraft’s flight path are equal to zero and the forces perpendicular to the aircraft’s flight path are also equal to zero. The forces are then said to be in equilibrium. 
    Answer B is incorrect because if the aircraft is accelerating, thrust must be greater than drag. Answer C is incorrect because the aerodynamic forces of lift, thrust, and drag are not being generated (although the forces on the airplane are in equilibrium). I hope you had fun participating in our knowledge poll. cheers!
