Why are smaller alcohols fully miscible with water while larger alcohols have lower solubility in water?

Question

A. In larger alcohols, the polar hydrocarbon chain cannot interact with polar water molecules and limits alcohol's ability to interact with water.
B. In larger alcohols, the non-polar hydrocarbon chain cannot interact with polar water molecules and limits alcohol's ability to interact with water.
C. In larger alcohols, the non-polar hydrocarbon chain cannot interact with non-polar water molecules and limits alcohol's ability to interact with water.
D. In larger alcohols, the polar hydrocarbon chain cannot interact with non-polar water molecules and limits alcohol's ability to interact with water.

Answer 1

A and D can't be right because of the "molar hydrocarbon chain" statement.
Between B and C you make the choice on whether H2O is a polar or a non-polar molecule.

Answer 2

H2O is polar so B right?

Answer 3

That's what I would choose.
