E. None of the above

I think solvents are always aqueous? but the answer is not B.
Please help me! Thanks!:)

[Nehal Banik]

Solvents are not included in the reaction quotient or equilibrium constant, because there is way for you to measure the concentration of a pure solid displaced in some liquid. Just know that liquids and solids are not used or even considered when doing ice boxes or calculating the equilibrium quotient.

[Glendy Gonzalez 1A]

Whenever solvents are liquids or solids they are not in included in equilibrium constant expressions. This is because the change in solvent concentration is insignificant.
