Anticoagulant rodenticides kill rodents by

Explanation:
Anticoagulant rodenticides kill by preventing the blood from clotting. They disrupt the vitamin K cycle in the liver, reducing the activity of vitamin K–dependent clotting factors (II, VII, IX, and X). Without these factors, blood cannot clot properly, so internal bleeding develops over days and leads to death. This mechanism explains why death occurs from hemorrhage rather than from nerve disruption, dehydration, or oxygen deprivation.
