A student investigated the conductivity and products of electrolysis for three different solutions, X, Y, and Z. Their results are shown in the table below.
| Solution | Solution conducts electricity | Product at cathode | Product at anode |
|---|---|---|---|
| X | yes | zinc | bromine |
| Y | no | none | none |
| Z | yes | hydrogen | oxygen |
Which of X, Y and Z are electrolytes?
Y only
X and Z only
Y and Z only
X, Y and Z
