The Easy-Gro agricultural company estimates that when 100x worker-hours of labor are employed on y acres of land, the number of bushels of wheat produced is f(x, y) = Ax^ay^b, where A, a, and b are positive constants. Suppose the company decides to double the production factors x and y. Determine how this decision affects the production of wheat in each of these cases:

a. a + b > 1

b. a + b < 1

c. a + b = 1
