Answer: (B)

Verified step by step guidance

1. Understand that the pancreas has both exocrine and endocrine functions. The exocrine part produces digestive enzymes, while the endocrine part produces hormones.
2. Identify the structures associated with the exocrine function: the pancreatic acini, which secrete digestive enzymes into ducts.
3. Recognize that the endocrine portion consists of clusters of cells that release hormones directly into the bloodstream.
4. Recall that these clusters are called pancreatic islets or islets of Langerhans, which regulate blood glucose by producing hormones like insulin and glucagon.
5. Eliminate other options: Brunner glands are found in the duodenum, and the main pancreatic duct is a duct, not an endocrine tissue.
