GIT Gastric function question

A 75-year-old male presented with a 6-month history of early satiety and with upper abdom- inal discomfort for many years. Physical exam- ination revealed mild epigastric tenderness. Esophago-gastro-duodenoscopy showed a large, ulcerated mass in the upper stomach, which was found to be cancerous. Surgery resulting in the removal of the gastric fundus was performed. After successful surgery, the patient was advised to eat small portions and to drink small volumes because of which of the following?

(A) almost complete absence of gastric motility
(B) distorted emptying of liquids
(C) inadequate mixing of large food boluses
(D) lack of receptive relaxation in the stomach
(E) weaker and slower propulsion of food toward the pylorus

lack of receptive relaxation!!.....not E because after gastrectomy there is fear of dumping syndrome...so no weaker propulsion issue..!!!

Correct Answer D is correct answer

(D) The receptive relaxation reflex is a feature of the oral stomach, composed of the fundus and upper stomach body. Without food, the orad stomach shows low frequency, sustained contractions that are responsible for generating a basal pressure within the stomach. When food enters the stomach, a reflex is initiated, which allows gastric accommodation of large increases in volume with only small increases in intragastric pressure.
