Is lift distribution over a wing can be modeled with the concept of circulation?

(a) True

(b) False

This question was addressed to me in an interview for internship.

Query is from Prandtl’s Classical Lifting-Line Theory topic in chapter Flow over Airfoils over Finite Wing of Aerodynamics

Best answer
Right answer is (a) True

Explanation: The lift distribution over a wing can be modeled with the concept of circulation. A vortex is shed downstream for every span wise change in lift. Modeling the local lift with local circulation allows us to account for the influence of one section over its neighbors.
