B. the water molecules are weaker than the attractive forces between the water molecules and the oil molecules.
C. the oil molecules are weaker than the attractive forces between the water molecules and the oil molecules.
D. the oil molecules are ionic and the attractive forces between the water molecules are covalent.

Answer 2

It's A.

Answer 3

oils are made of carboxylic acid group and alcohol group. Both of these have hydrogen bonds. In water, there are also hydrogen bonds. when they are to react, I believe when they react, the OH part of water reacts with the OH of the alcohol, being left with the acid part. and it is said that acids are readily soluble, which explains why their bonds are weaker than those of water. the reason why the answer is A.
