Mock Q on Econ w/ Twisted answer understand, question, because, product, returns

wilslm

In the SR, the Average Product of labor:
a) is increasing when the total product of labor is increasin
b) is at maximum where it intersects the Marginal product of labor
c) is upward-sloping if the firm is eperiencing diminishing marginal returns to labor
So the answer is B. However, the issue i have with this question is that it could also be A, because the Average Product of labor is also 1st increasing and then decreasing as diminishing marginal returns take effect.
I dont understand why they threw 2 legit answers in there. Anyone got some clarification on this?

So from the range of 1-3 labor units, is AP not increasing?

Diminishing returns to labor. AP increases for the first few laborers but decreases over time. Yes AP increases between 1 and 2 but from 2 to 10 it decreases. I see your logic but B is the best answer as it happens 100% of the time.

a) is increasing when the total product of labor is increasin
Answer A is implying it ALWAYS increases when total product of labor is increasing, that is not correct.
