C Correct answer
Explanation

Bernoulli's principle explains wing lift: the airfoil shape creates faster airflow over the curved upper surface, reducing pressure there relative to the higher pressure below, generating lift. While Newton's 3rd law also applies (action-reaction with downwash), Bernoulli's principle is the standard answer for the primary lift mechanism. D'Alembert's paradox relates to fluid dynamics drag, and Boyle's law concerns gas pressure-volume relationships.
