Submandibular space
Buccal space
Sublingual space
Palatal region

The correct answer is: Submandibular space

An acute periapical abscess originating from a mandibular third molar generally points and drains in the submandibular space. This is because the submandibular space is the most common area for infection to spread from the mandibular third molar. The sublingual and palatal regions are also possible areas for infection to spread, but they are less likely. The buccal space is not a common area for the abscess to drain because the mandibular third molar is usually located more inferiorly and posteriorly in the mouth, away from the buccal space. Therefore, the most likely and correct answer is the submandibular space.
