Approximately 1/10 part of an iceberg floating in the sea remains above the surface of the sea. This is due to the difference in densities between ice and seawater, where the density of ice is about 90% that of seawater, causing most of it to remain submerged.

Approximately 1/10 part of an iceberg floating in the sea remains above the surface of the sea (B). This is due to Archimedes’ principle, which states that the buoyant force acting on a submerged object is equal to the weight of the fluid displaced by the object. Icebergs are made of freshwater ice, which has a density of about 0.92 g/cm³, while seawater has a density of about 1.025 g/cm³. Because the density of ice is lower than that of seawater, only about 1/10 of the iceberg’s volume is above the surface, while the rest is submerged. This ratio can vary depending on factors such as the iceberg’s shape and density distribution. Option (B) 1/10 accurately represents this fraction, making it the correct answer.
