L and M are interchangeable. You can eliminate answers D and E right off the bat.
A is CORRECT. G is the only variable that requires another variable to be with it. You can only repeat one variable, so you can’t place G and O together twice (for example.)
The only way to have G repeat would be to put G with O, and with J. But if G goes in 3 with O, G can’t repeat. Nothing that goes in 3 can repeat.
B is wrong because H can go in the fourth row as long as it also goes in row 1, before J.
C is wrong. K can go in the fourth row as long as K is also in row 1 or 2.
