For this question i firstly thought thatif reactant exceed product than product has to be unstable in order to proceed reaction backward so that's why i asked u

option A if stability of product is more than reactant than concentration of product will be more than reactant hence K > 1 if stability of reactant is more than product than conce...

if K>1 products is favoured...if K<1 reactants is favoured...if K=1 neither reactants nor products is favoured
