Answer

X

Because

The pattern needs the X to repeat

There is a pattern of 5 possible symbols: X # O @ !.

The pattern repeats in a spiral pattern around the square (Starting at the left top corner).

O

Because

When you draw the bottom-left top-right extended diagonals, there are duplicate symbols sitting next to each other on every line

(I think MacGyver88's solution is simpler, so it is probably what the author thought about).

From the six columns only the fourth contains the same symbol 3 times, namely the symbol $$O$$. In addition to that, none of the rows contains the same symbol 3 times. If we replace the question mark which is on fourth row with the symbol $$X$$ then on the fourth row the symbol $$X$$ appears 3 times as well.

Or....

Each row has exactly one symbol duplicated. In the ? row the X is already duplicated, meaning the answer must be #, to have all 5 symbols.

• This fails in the third row, where both O and @ are duplicated, or the 5th with ! and # Commented Oct 23, 2020 at 18:55
