A 60-year-old man presents to the GP with symptoms of heartburn and a mild cough due to gastro-oesophageal reflux disease (GORD). He has a BMI of 30.

Acid reflux can cause adaptive changes in the cells lining the oesophagus from one differentiated cell type to another. This cellular change, or metaplasia, is known as Barrett's oesophagus.

Which of the following best describes the metaplastic change that cells undergo in Barrett's oesophagus?
a
