None of the above

Detailed explanation-1: -Lipids are hydrophobic means water hating. They are water insoluble. Lipids are non-polar molecules while water is polar molecule, so there is no way for water to attach to a lipid molecule.
Detailed explanation-2: -Most lipids are non-polar (having no charged areas) or only slightly polar, with a very few charged areas. Water mixes with hydrophilic (water-loving) compounds by sticking to their charged groups. Since lipids lack charged groups, the water molecules have nothing to stick to and don’t mix with them.
Detailed explanation-3: -The characteristic that all lipids have in common is that they are nonpolar molecules, which means they do not dissolve in water. Oils are a common type of lipid.
Detailed explanation-4: -Lipids are fatty, waxy, or oily compounds that are soluble in organic solvents and insoluble in polar solvents such as water.
