The rate and direction of reactions are greatly influenced by the

law of mass action only
molecular concentration only
both of the above because they relate to the same principle
none of the above

Both of the above because they belong to the same principle. I hope this helps!

:-)

The correct answer is option C, both of the above because they relate to the same principle

The Law of mass action states that rate of  a chemical reaction depends on the active masses of the substance and also the rate of chemical reaction is directly proportional to the product of the molecular concentration (active masses) of reactants. Thus both the option A and B points towards the same theory

For example –  

In the reaction,  

A + B ↔ X +Y  

Rate of forward reaction  is directly proportional to the product of  [A] [B]

thinking it would be d not too sure but i think it's right
