Where is a brinicle found?

Option D

A brinicle (brine icicle, also known as ice stalactite) is a downward-growing hollow tube of ice enclosing a plume of descending brine that is formed beneath developing sea ice.

As seawater freezes in the polar oceans, salt brine concentrates are expelled from the sea ice, creating a downward flow of dense, extremely cold and saline water with a lower freezing point than the surrounding water. When this plume comes into contact with the neighboring ocean water, its extremely cold temperature causes ice to instantly form around the flow. This creates a hollow stalactite, or icicle, referred to as a brinicle.
