I think it’s true
(Not sure)
Answer: Option (B) is correct.
Explanation:
Correct option: Decreasing marginal product.
Marginal product is the change in the level of output, when there will be an extra input employed in the production of a certain commodity.
So, Marginal Product = 
Where,
Q = Output
I = Input
Marginal product of 1st bag = 500
Marginal product of 2nd bag =
= 300
Marginal product of 3rd bag =
= 100
∴ From the above calculations, we can seen that as we employed one more bag of seeds as a result marginal product goes on diminishing.
Hence, Joan's production function exhibits decreasing marginal product.
