The correct option is this: THE MUSCLES AT THE END OF THE ESOPHAGUS IS NOT ABLE TO CLOSE, WHICH ALLOW STOMACH ACID AND DIGESTED FOOD TO GO BACK UP INTO THE ESOPHAGUS.

Heartburn is also called acid reflux and it occurs, when the sphincter muscle at the tail end of the esophagus relaxes when it ought not to, thus allowing stomach acid to flow back into the esophagus. Heartburn may be caused by some types of food, alcohol or drugs.
