Answer: D- Cholinesterase inhibitors are indirect-acting miotics.

Cholinesterase inhibitors work by inhibiting the enzyme that breaks down acetylcholine, thereby increasing the amount of acetylcholine available to activate parasympathetic receptors. Cholinesterase inhibitors are indirect-acting miotics, which means they don't act directly on the end organ. Pilocarpine, Carbachol, and Betaxolol are all direct-acting miotics.
