The runway orientation is made so that landing and takeoff are A. Against the wind direction B. Along the wind direction C. Perpendicular to wind direction D. None of these

The correct answer is: A. Against the wind direction.

When an airplane takes off or lands, it needs to overcome the force of gravity. The faster the airplane is moving, the less force of gravity it needs to overcome. Therefore, airplanes take off and land into the wind. This increases their speed and makes it easier for them to take off and land.

Option B is incorrect because airplanes do not take off and land along the wind direction. If they did, they would be moving at the same speed as the wind, and the force of the wind would not help them to take off or land.

Option C is incorrect because airplanes do not take off and land perpendicular to the wind direction. If they did, they would be moving perpendicular to the force of the wind, and the force of the wind would not help them to take off or land.

Option D is incorrect because airplanes do take off and land into the wind. This is the only option that is correct.
