Given below are two statements:
Statement I: In preference to a nitrogen-oxygen mixture (present in air), a helium-oxygen mixture is used by divers in deep sea because helium is less soluble in blood than nitrogen at high pressure under the sea.
Statement II: In preference to a nitrogen-oxygen mixture (present in air), a helium-oxygen mixture is used by divers in deep sea because it can readily mix with oxygen than nitrogen.
In the light of the above statements, choose the correct answer from the options given below:
