Anesthesia is categorized into four broad techniques: general anesthesia, regional anesthesia, local anesthesia, and monitored anesthesia care. In practice, regional anesthesia is often delivered by specific methods called peripheral nerve blocks, which numb a defined area by injecting local anesthetic near particular nerves. Monitored anesthesia care (MAC) provides sedation and analgesia without forcing the patient into full general anesthesia.

Why this option fits best is that it names the four modalities in a way many curricula teach them, with a concrete example of a regional technique (peripheral nerve blocks) alongside the broad regional approach and MAC. It highlights that regional anesthesia can be achieved through targeted nerve blocks, while MAC stands apart as sedation/analgesia without complete unconsciousness.

Other groupings mix in concepts that aren’t considered separate techniques in the same four-category framework (for example, labeling local infiltration as a separate technique instead of as a regional approach, or combining neuraxial and limb blocks in a way that obscures the distinct techniques). This makes them less aligned with the standard four-technique taxonomy.
