If K > 1 at 25°C and 1 atm of pressure, then which statement is true about the reaction's equilibrium?

a. There is always more reactant than product at equilibrium under all conditions.
b. There is more product than reactant at equilibrium at these conditions.
c. There is always more product than reactant at equilibrium under all conditions.

I believe the answer is B. I do not think it is under all conditions. Please help.

    Frankly, I'm not sure how to answer this. If all conditions means temperature changes, also, we know K changes (so K may not be >1 anymore) with temperature and when K changes products/reactants may change. But with K not > 1 anymore that changes the question. I'm inclined to think that the question means as long as K>1 and the system is at equilibrium, then c would be the correct answer. Here are my two answers.
    If ALL means temperature changes then I go with b as the correct answer; otherwise, c is correct. Scott or Bob Pursley may have a different take on this.
