Seems Wright to me

How much air is moving beneath the wings if a conveyor is matching wheel speed?
Air pressure beneath the wing is what creates lift
Like propellers, jet engines propel themselves (and the plane attached to them) through the air, regardless of ground speed.

Are you sure you graduated from high school? First off, no wings, no lift, no flight. Jet turbine engines do not cause a plane to fly. Wings cause a plane to fly. You need air speed for lift to occur. Otherwise all you have is ground speed.
You might want to back it down a few gears. The conveyor belt would have ZERO effect in preventing the jet from moving forward and creating enough speed for lift. Think about it. maybe you should have gone to a different high school? Sorry, couldn't resist

You must have not understood the premise of the question to start with. The plane doesn’t move forward, at all, never. Think about it. The whole point of including the conveyor belt is the trick of the question. Chain the plane in place. The engines, whether turbine or propellor will not cause lift on the wings. Engine speed could be maxed out. If air speed is zero, then there is zero lift.

If the plane's propellers/jet engines are pulling it through the air at the same speed the conveyor belt is moving backwards, then it will not move forward or backwards, but it may lift off the conveyor belt (straight up) if that speed is at least as fast as its minimum airspeed for liftoff.The plane moves. The wheels roll. The conveyor rolls at a matched speed in opposite direction. That is the premise.
Of course it takes off. The plane don't give a crap what the wheels are doing.
Think of a float plane.
No.
Zero airspeed.....
