**Core Concept**
Ester local anesthetics are a class of amide-linked compounds that undergo hydrolysis by the enzyme pseudocholinesterase (also known as butyrylcholinesterase) in the plasma, resulting in the formation of a para-aminobenzoic acid (PABA) metabolite. This metabolic pathway is distinct from that of amide local anesthetics, which are primarily metabolized by the liver.

**Why the Correct Answer is Right**
The correct answer is related to the metabolism of ester local anesthetics. Pseudocholinesterase is the enzyme responsible for hydrolyzing ester local anesthetics, such as cocaine, procaine, and tetracaine, into PABA and the parent compound without the ester group. This metabolic pathway is a key characteristic of ester local anesthetics.
