Default ???

this question has got me scratching my head, gastrin seems like the ovious choice the problem is the qualifier of 'fasting'. GRP is tempting too
tempted to choose motilin b/c of gasting but just read that in addition to MMC it stims the release of somatostatin so it cant stim gastric acid also.
so i will stick with gastrin
pls what is the correct ans?
thanks
