ANS:D - a parabolic path.

From a nozzle exposed to atmosphere, the liquid jet typically traverses a parabolic path. When liquid is forced through a nozzle into the atmosphere, it forms a jet that is subject to gravity and air resistance. The shape of the liquid jet is influenced by various factors including the velocity of the liquid, the angle of discharge from the nozzle, and the properties of the liquid. Under ideal conditions and neglecting air resistance, the liquid jet follows a parabolic trajectory due to the combined effects of gravity and the initial velocity imparted by the nozzle. This parabolic path is similar to the trajectory of a projectile launched into the air. However, in real-world situations, air resistance may cause the liquid jet to deviate slightly from a perfect parabolic path. Additionally, factors such as turbulence, wind, and the specific characteristics of the liquid and nozzle can also affect the shape and behavior of the liquid jet. Overall, while the liquid jet may not follow a perfect parabolic path in every circumstance, a parabolic trajectory is a common and practical approximation for describing the behavior of liquid jets discharged from nozzles into the atmosphere.
