Which option correctly identifies a fixed combination without beta blockers?

Explanation:
Fixed combinations in glaucoma therapy are made to simplify dosing by putting two drugs in one drop. To be without beta blockers, neither component can be a beta-blocking agent like timolol. Brinzolamide is a carbonic anhydrase inhibitor and brimonidine is an alpha-2 adrenergic agonist, and together they form Simbrinza, a fixed combination with no beta blocker. The other listed pairings all include timolol, a beta blocker, so they don’t meet the requirement. Therefore, Brinzolamide 1% with Brimonidine 0.2% (Simbrinza) is the correct choice.
