Both secretin and cholecystokinin (CCK) are hormones involved in the hormonal control of the gastrointestinal (GI) tract. The pancreas is stimulated by both secretin and CCK.

Secretin is released by the small intestine in response to the presence of acidic chyme, and it stimulates the pancreas to secrete bicarbonate, which helps neutralize the acidity of the chyme.

Cholecystokinin (CCK) is also released by the small intestine, specifically in response to the presence of fat and protein in the chyme. CCK stimulates the pancreas to release digestive enzymes that aid in the digestion of fats and proteins.

Hence, the correct answer is option 3.
