In the reaction b + kl + h, if an additional b is added, the result will be more k will be produced more l will be required the reaction will slow down more l and h will be produced

The effect of adding further B is that it favors the forward reaction which means more products will be produced upon the addition. This obeys Le Chatelier's principle which states that any disturbance incurred to the equilibrium system shall be dealt such that the disturbance is countered to and attain equilibrium again.

Ultimately...
D. more L and H will be produced 

Ithink that b is correct but just in case wait to see if someone else answers

You should provide a picture to show where the arrow is pointing and which information that is given. but there are 3 branches of the government, legislative, executive, and judicial. legislative makes laws, executives pass laws, and judicial are the courts
