Step-by-step explanation:
Based on the article by Balter (2005), the correct statement is option c. The likelihood of a person having crowded teeth is greater in countries where people eat harder foods. The article mentions that the eating of softer foods as a result of cooking meat and plants alleviated the need for large chewing teeth and jaws. Over time, this led to smaller teeth, which resulted in crowded teeth. Therefore, the likelihood of crowded teeth is greater in countries where people eat harder foods.
