Why not D? (4?)
When R is assigned to 5:
J can be in position 2 (when P = 1, N = 2, F = 3, M=4, T = 4)
J can be in position 4 (When P = 1, M = 2, T = 2, F = 3, N = 4)
J can be in position 1 (When N = 1, P = 2, F = 3, M = 4, T = 4)
When R is assigned to 4 or 2:
J can be in position 5 (when M = 1, P = 2, F = 3, T = 3, N = 5)
Then is 4 different positions. Where am I incorrect?)

I watched to the explanation video and found the question stem confusing. The question is asking what is the maximum number of different lockers J can be assigned once R is assigned. How is it different from what is the maximum number of different lockers can J be assigned (without the condition of R first being assigned) since R has to be assigned anyways? :(

Hi, in the former scenario you are describing, we are being asked once R is decided, how many can J go in. That is, once R is placed, there are only four places left for J. However, if R has not yet been placed, then J can go in any of the five open spots.
