The correct option is
B R
____□____□____□____ (South facing)
____□____□____□____ (North facing)
Q is in the bottom row. T is in the bottom row
R next to U are in the top row. which means S is in the bottom row because U and S are diagonally opposite.
So P gets in the top row.
Q and S cannot be next to each other. so T is in between Q and S in bottom Row
And U is in the center to be diagonally opp to S in the top row.
so we have
____R____U____P____ (S facing)
____Q____T____S____(N facing)
OR
____P____U____R____ (S facing)
____Q____T____S____(N facing)
OR
____R____U____P____ (S facing)
____S____T____Q____(N facing)
OR
____R____U____P____ (S facing)
____Q____T____S____(N facing)
In every case T is between Q and S.
If the flats of P and T are interchanged then R will be opposite of U
