Answer»

The correct option is (b) OVERPRODUCTION of acid and over relaxation of lower esophageal sphincter

The BEST explanation: GERD or Gastro Oesophageal Reflux Disease is when acid and PEPSIN from the stomach flows backward up into the ESOPHAGUS OFTEN called heartburn. Gastric juice contains both acid and pepsin. It can happen due to overproduction of acid/pepsin or over the relaxation of Lower Esophageal Sphincter.
