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?

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.

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.

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