Not 100% sure but B sounds the most likely from what I've read...
During stress, hormones like epinephrine and norepinephrine are secreted at higher levels. The sympathetic nervous system is also activated at that time. There is also an increase in blood pressure and improper insulin-dependent glucose disbursal. All of these lead to insulin resistance, and central obesity. Vascular complications also increase. The Basic Metabolic Rate (BMR) lowers down during the same because of disruption in the digestive system.

I would suggest Mexican and Latin foods since they most likely rice and corn based. You can also try out Caribbean its a pretty good option and it has really good tasting food that are gluten free. And even if the food isn’t gluten free Mexican and Latin food can easily be converted into a gluten free version of the food.
Enjoy.
