Option d) Reactants will decrease, product will increase
An increase in temperature causes an increase in the speed of the reaction, that is, it increases the speed with which the reagents are consumed to form product. If the temperature is increased in an equilibrium reaction, the equilibrium will shift towards the formation of the products, that is, the concentration of the reagents decreases and the concentration of the products increases.
