Gas and bloating are often caused by a condition called hypochlorhydria, which is an insufficient amount of stomach acid. This can also be caused by inadequate digestive enzymes, which are necessary for breaking down food and preventing gas and bloating. Intense physical exercise and a low-fat diet may contribute to gas and bloating, but they are not a common cause. Regular consumption of starches can also cause bloating, but it is not necessarily a common cause and does not address the issue of gas. Therefore, A is the best answer that accurately reflects a common cause of gas and bloating.
