Answer»

Correct choice is (c) Polar

Explanation: Water is a universal solvent. It has the ability to dissolve the greatest number of SUBSTANCES than any other solvent. The highly polar nature accounts for this special feature as the water molecule BEARS a slightly positively CHARGED hydrogen ion and two highly negatively charged oxygen IONS. Since, it becomes attracted to many different types of molecules it is known as the ‘universal solvent’.
