Detailed Solution

Curtain will get pushed outside the room because if a strong wind moves along the corridor, then the air pressure increases and the curtain gets pushed outside the room.(Air moves from the region of higher pressure to the lower pressure. The greater the difference in pressure, the faster the air moves.)
Thus the correct statement would be, a curtain hanging at the entrance of a room parallel to the corridor will get pushed outside the room if strong wind blows along the corridor.
