Solution

The correct option is C Assertion is incorrect but Reason is correct
Sugar is a covalent compound that is soluble in water, because it contains $O - H$ groups that can form hydrogen bond with the water. So,Covalent bonds are not broken when sugars are dissolved in water. Hence, Assertion is incorrect.
Covalent bond by definition is formed when electrons are shared by two or more atoms. Hence, the reason is correct.
