Answer 1

fats and oils are insoluble in water but soluble in acidic or alkaline solutions

• the presence of -OH , hydroxyl group in carbohydrate makes them hydrophillic that is they dissolve easily in water.
• the solubility of protein in water depends on the three dimensional structure of protein.

hence, the correct options are

a. fats
