Answer 1

The correct option is (d) cardiac sphincter and pyloric sphincter

To explain I would say: The sphincters are basically a band of muscles that regulate the opening and closing of any opening in the body. The sphincter muscles towards the esophagus are called the cardiac sphincter because they are close to the heart or the lower sphincter because it brings the food down. The opening towards the intestine is called the pylorus and the muscles guarding them are the pyloric sphincter.
