Do I see a 100 amp breaker? I think this is the main panel and it should be bonded. So if this panel is bonded then if there is no green screw to show for ground bus, then what is the difference between the the two bus bars? I would like to know the answer.

And where does it indicate that in the photo supplied?
As both bus bars are bonded to the panel (and to each other), it matters not which side the neutrals and grounds are wired to. In fact, many bus bars have a mix of grounds and neutrals.
If one of your choices were that the neutrals are double luggged, it would be correct.
Comments anyone? I dont believe the double lugs were a choice.
I still maintain that "nothing" is the correct answer, in lieu of the choices and lack of information. Where is it indicated in this photo that the neutrals need to be on the "right" side.

Thanks, Jae.
Bottom line is that, based on this photo, there IS something wrong with the panel. Unfortunately, it was not one of the choices.
Neutrals can indeed be double lugged, PROVIDED that the panel is rated for it. This issue is just as relevant as the neutrals and grounds being "reversed", where the manufacturer's specs state as much.
I would have flagged the double lugged neutrals long before the reversed witring thingie.

I think ya meant to say "grounds" can be double/triple lugged if the panel is rated for that ... 
FYI ... Neutrals are not and never were allowed to be double lugged per the UL standard for panels from at least as far back as the 1960's, which was made a direct NEC restriction in 2002 due to confusion on that. Very common defect as a result ...

I am absolutely amazed sometimes by how much thought goes into doing things wrong

Assuming this is a sub-panel, the neutral should be floating and the grounds separted from the neutral and bonded to the sub-panel enclosure. The photos show two terminal blocks; one on each side of the bus bar. These are factory neutral terminal blocks and come from the factory on a plastic insulator and therefore are floating. The problems are:
1. The insulated neutral from the main panel is on the ground side and should be moved to the neutral side.
2. The bare ground wire on the neutral terminal block should be moved to the ground terminal block.
3. The neutral and grounds are connected via the factory installed metal strap that runs under the bus bar. This bar can be physically broken to separate the neutral and grounds.
4. One last thing, the equipment ground side should be bonded to the enclosure using a bond screw or strap. Can't tell from picture whether this has been done.
