A Correct answer
Explanation

Glyphosate targets EPSP synthase (5-enolpyruvyl shikimate-3-phosphate synthase) in the shikimate pathway. Bromoxynil is detoxified by nitrilase enzymes. Sulfonylureas inhibit acetolactate synthase (ALS), a key enzyme in branched-chain amino acid synthesis. Dalapon is metabolized by dehalogenase enzymes. Option A correctly matches each herbicide to its target enzyme.
