B)Bernoulli's equation
C)the equation of continuity
D)Archimedes' principle
E)Pascal's principle

Bernoulli's equation is the best choice to explain this movement of the curtain. Bernoulli's equation relates fluid velocity, pressure, and height. When wind passes over the open window, the air pressure outside the window decreases, making the pressure inside the room higher. This pressure difference causes a flow of air from high pressure to low pressure, which leads to the movement of the curtain. Bernoulli's equation explains this phenomenon in terms of the pressure difference and velocity of air, which is relevant to the movement of the curtain.
