Which of the following pairs of substances can represent solutions \text{X} and \text{Y}?

1. (A)\text{X} = \text{HCl}_{\text{(aq)}}, \text{Y} = \text{H}_2\text{O}
2. (B)\text{X} = \text{KOH}_{\text{(aq)}}, \text{Y} = \text{H}_2\text{O}
3. (C)\text{X} = \text{HCl}_{\text{(aq)}}, \text{Y} = \text{KOH}_{\text{(aq)}}
4. (D)\text{X} = \text{KOH}_{\text{(aq)}}, \text{Y} = \text{HCl}_{\text{(aq)}}
