Final answer:
Bromadiolone is the example of a single-dose anticoagulant rodenticide listed, as it disrupts blood clotting in rodents.
Step-by-step explanation:
The example of a single-dose anticoagulant rodenticide among the options provided is c) bromadiolone. Anticoagulant rodenticides work by interfering with the blood clotting process, leading to internal bleeding and eventually death in rodents after consuming a lethal dose. While bromethalin (a) and zinc phosphide (b) are rodenticides, they do not work as anticoagulants.
Bromethalin is a neurotoxin and zinc phosphide releases phosphine gas in the stomach. Vitamin D3 (d) although used in rodenticides, does not work as an anticoagulant but rather causes hypercalcemia.
