A. INACTIVE PRECURSOR OF THE ENZYME PEPSIN THAT DIGESTS PROTEINS IN THE STOMACH.
Explanation:
Pepsinogen is the inactive precursor of pepsin produced by the chief cells of the stomach lining. The stomach walls are lined by majorly two types of cells; the chief and the parietal cells. Chief cells secretes pepisinogen and parietal cells secrete hydrochloric acid in the stomach lining. The chief cells upon the signals of increased protein substance in the stomach produces pepsinogen which upon it release, it is activated to the active enzyme Pepsin by the hydrochloric acid from the parietal cell.
