Thin infinite uniformly charged planes produces uniform electric field therefore option 2 and option 3 are obviously wrong.
And as positive charge density is bigger in magnitude so its field along Y direction will be bigger than field of negative charge in

X

direction and this is evident in option 1 so it is correct.
