Certain cells that line the stomach synthesize a digestive enzyme and secrete it into the stomach. This enzyme is a protein. Which of the following processes could be responsible for its secretion?
A. endocytosis.
B. exocytosis.
C. phagocytosis.
D. passive transport.

Exocytosis is a process that helps in transport secretory products to the plasma membrane through the cytoplasm in a cell. In this process, the materials are transported out of the cell with the help of vesicles.

Some of the examples of the exocytosis are the secretion of the enzymes, proteins, peptide hormones and antibodies from the cell linings of the stomach that help in the digestive process.

Thus, the correct answer is option B. exocytosis.
