Lowering the flaps from 30 degrees to 40 degrees will result in a large increase in drag.

Here's why:

Flaps are used on the wing of an aircraft to increase the amount of lift that the wing produces. They do this by increasing the camber of the wing, which increases the wing's lift coefficient.

When the flaps are lowered from 30 degrees to 40 degrees, the camber of the wing is increased even more. This results in a larger increase in lift, but it also results in a larger increase in drag.

Drag is the force that opposes the motion of the aircraft through the air. It is caused by the air resistance that the aircraft encounters as it moves. When the flaps are lowered to 40 degrees, the increased camber of the wing causes the air to flow over the wing in a less streamlined manner, which increases the air resistance and therefore the drag.

So, the correct answer is d. Large increase in drag.
