Which of the following has the shortest half-life?

Explanation:
The main idea here is how quickly a drug is cleared from the bloodstream, which is reflected in its half-life. Articaine stands out because it has an ester linkage that is rapidly hydrolyzed by plasma esterases. This rapid breakdown in the blood means it is cleared from circulation sooner than the others, giving it the shortest systemic half-life. The other agents are amide-type anesthetics, metabolized primarily in the liver, so they remain in the system longer and have longer half-lives.
