Liquids $X$ and $Y$ do not react with each other, and they have the same boiling point. If a given volume of $X$ is shaken with an equal volume of $Y$, a liquid mixture $Z$ is formed. The average intermolecular forces in liquid $Z$ are stronger than the average forces in $X$ and the forces in $Y$. Which conclusions from this information are correct?
- A1, 2 and 3 are correct
- B1 and 2 only are correct
- C2 and 3 only are correct
- D1 only is correct
