C Correct answer
Explanation

Dietary fiber consists of plant-based carbohydrates that human digestive enzymes cannot break down. Unlike sugars, starches, and proteins that get digested and absorbed, fiber passes through the digestive system largely intact. This is actually beneficial: it adds bulk to stool, promotes regular bowel movements, and supports gut health. 'Inorganic' refers to minerals, not indigestible food components. 'Fibroids' are benign tumors (muscle tissue), not food components. 'Tumors' are abnormal tissue growths, unrelated to nutrition.
