The graph of b versus a is a hyperbola. Draw a graph and you'll see that the largest value of b that satisfies b < 13 and a is a positive integer is b = 21/2 corresponding to a = 3.

Sorry since we don't have the possible answers we just can quess what b might be
b/(b-7)=a
a can go to extreme and so b can go to extreme as well
