i) Answer Y, because activation energy is low
ii) Answer Z, because the it has largest negative delta G
iii) Answer Z, due to large negative delta G, the concentration of products is higher than reactants hence Keq is larger
iv) Answer X, due to positive delta G, the concentration of reactants is higher than products hence Keq is smaller
v) Answer X, due to small energy gap between transition state and products
vi) Answer Z
Hence among given options, Answer A
