b) The lesion is likely to be adenomatous and should be removed by endoscopic mucosal resection (EMR)
c) The lesion is likely to be a neuroendocrine tumour (NET) and should be removed surgically
d) The lesion is likely to be a gastrointestinal stromal tumour (GIST), requiring annual surveillance
e) None of the above
