In the lift equation, if air density doubles while velocity and wing area remain constant, lift will do what?

Explanation:
Lift scales with air density when speed and wing area are constant. In the lift equation L = 0.5 ρ V^2 S Cl, if velocity V and wing area S (and Cl) are unchanged, the lift is directly proportional to ρ. Doubling the air density makes the product 0.5 ρ V^2 S Cl twice as large, so lift doubles. The other options would require changing velocity, area, or the lift coefficient, which aren’t in play in this scenario.
