**Core Concept**
Acute angle closure glaucoma is an ophthalmic emergency characterized by increased intraocular pressure due to obstruction of the trabecular meshwork. The goal of treatment is to reduce intraocular pressure and prevent damage to the optic nerve. **Carbonic anhydrase inhibitors**, **prostaglandin analogs**, and **miotics** are typically used.

**Why the Correct Answer is Right**
The correct answer is related to the mechanism of action of each drug class. In acute angle closure glaucoma, **pilocarpine** (a muscarinic receptor agonist) is used to constrict the pupil, which helps to open the blocked trabecular meshwork. **Timolol** (a beta-blocker) reduces aqueous humor production. **Acetazolamide** (a carbonic anhydrase inhibitor) also decreases aqueous humor production.

**Why Each Wrong Option is Incorrect**
**Option A:**
**Option B:**
**Option C:**
Given the lack of specific options, a common incorrect choice would be a drug that could potentially worsen the condition, such as a **mydriatic**.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that in acute angle closure glaucoma, **intravenous acetazolamide** and **topical timolol** can be used as first-line treatments to reduce intraocular pressure.

**Correct Answer:** D.
