NFHS Basketball Rules Changes Test Question

[PSidbury]

This question is driving me batty:

If a team jersey contains a visible manufacturer's logo/trademark/reference, all of the following are correct, EXCEPT:
a) It may not exceed 2 1/4 square inches with no dimension more than 2 1/4 inches.
b) It may be visible on the front of the jersey and on the back of the jersey.
c) It may not be located more than 5 inches below the shoulder seam on the front of the jersey.
d) It may be located in either side seam.

3-4-2a
A single visible manufacturer's logo/trademark/reference is permitted on the team jersey, not to exceed 2 1/4 square inches with no dimension more than 2 1/4 inches. The manufacturer's logo may be located no more than 5 inches below the shoulder seam on the front of the jersey, or 2 inches from the neckline on the back of the jersey; or in either side insert.

I have copied the question verbatim. Yes, including that "may not be located more than", which to me equates to "may be located no more than".
Is a side insert the same as a side seam?

I am at a loss.
All 4 potential answers seem to be covered in the 3-4-2a description.
But, then again, maybe not.
What am I missing?

Thanks,
Paul
