Answer:
The correct options are A, C and D.
Explanation:
The given figure shows an unfolded paper. It is a square sheet.
Here the line of symmetry are diagonals FN, AK and midline CM, OI. All of these lines are intersecting at point R.
Diagonals of square bisect each other, therefore R is midpoint of FN.

(OI is line of symmetry)
(AK is line of symmetry)
(FN is line of symmetry)
(FN is line of symmetry)
