(1) Water can be broken down by chemical means.

(3) Water has a heat of fusion of 334 J/g.

(4) Water is a poor conductor of electricity.

I believe the correct answer from the choices listed above is option 1. Water is classified as a compound because it can be broken down by chemical means. This process is called electrolysis where the products are H2 and O2. Hope this answers the question. Have a nice day.
