- boiling point of A greater than B; average molecular mass of A greater than B
- boiling point of A greater than B; average molecular mass of A smaller than B
- boiling point of A smaller than B; average molecular mass of A greater than B
- boiling point of A smaller than B; average molecular mass of A smaller than B
