Which is the best explanation of her results?

Answer 1

The sample was broken down by the electric current and formed a new substance that could burn. Therefore, the original liquid is a compound.

Answer 2

The sample was broken down by electric current and formed a new burnable substance The initial substance, then, is a compound.
