1-Suppose agricultural output requires only two inputs, labor and land. The quantity of land available is fixed; the quantity of labor is variable. Then, as labor quantity is increased in order to increase output quantity, the law of diminishing returns will begin to operate, and:

a.the ratio of labor to land will increase, but the ratio of land to output will fall.

b.both the labor-land ratio and the land-output ratio will fall.

c.both the labor-land ratio and the land-output ratio will increase.

d.the labor-land ratio will fall, but the land-output ratio will not change.

e.the labor-land ratio will increase, but the land-output ratio will not change.
