Which phenomenon causes increased drag on an aircraft wing near stall?

💡 Explanation

Boundary layer separation results in increased drag because transition to turbulence increases momentum exchange, reducing the pressure difference and lift, therefore, separation increases profile drag rather than reducing lift due to direct friction effects alone.
