Correct Answer

Explanation

Water has the ability to dissolve many substances because its molecule has a structure with one positive end and one negative end. The water molecule (H2O) is polar, meaning it has a partial negative charge near the oxygen atom and partial positive charges near the hydrogen atoms. This polarity allows water molecules to interact with and surround ions and polar molecules, facilitating the dissolution of a wide range of substances in water.
