Answer: (C)

The primary function of the stool guaiac test is to find hidden blood in the stool. This test is utilized to screen for gastrointestinal bleeding, which may indicate a range of conditions, including polyps, diverticulosis, or colorectal cancer. The guaiac test specifically looks for the presence of hemoglobin, which is a protein found in red blood cells, in the stool. Finding blood that is not visible to the naked eye can be crucial for early diagnosis and treatment of serious conditions affecting the gastrointestinal tract.
