The ophthalmic drug that can cause discomfort in the brow area is:

Explanation:
Brow discomfort is a classic side effect of pilocarpine. This drug is a direct muscarinic (parasympathomimetic) agent that stimulates the iris sphincter and the ciliary muscle. The ciliary muscle constriction and the resulting accommodation can pull on surrounding orbital tissues, producing brow ache or a fore-head–level discomfort, especially with instillation or higher doses. The other options tend to cause stinging, burning, conjunctival redness, or systemic effects, but not the characteristic brow ache associated with pilocarpine’s muscarinic stimulation.
