C. Resistance within the trabecular meshwork reduces aqueous humor outflow.
Explanation: In open-angle glaucoma the drainage angle is anatomically open but increased outflow resistance (usually at the trabecular meshwork) raises IOP and causes progressive optic nerve damage. (A describes angle‑closure; B is incorrect mechanism; D describes normal‑tension glaucoma.)
