With standard chokes, Full Choke is the tightest. However, there are non-standard chokes for SOME shotguns (used by turkey hunters) that are Extra Full Choke.
The correct answer is Super full.

Amount of muzzle constriction
Common shotgun chokes, from the tightest to the widest pattern, include Full, Modified, Improved Cylinder, and Cylinder. The Full choke provides the tightest shot pattern, ideal for long-range shooting, while the Modified choke offers a slightly wider spread suitable for medium-range targets. Improved Cylinder allows for an even broader spread, making it effective for close-range shooting, and the Cylinder choke has no constriction, resulting in the widest pattern for short distances.
Cylinder bore- which is no constriction at all.
If you mean a choke bored barrel, it designates the amount of constriction a shotgun barrel has.
The choke that provides the tightest shot pattern is the "Full" choke. This choke constricts the shotgun's barrel more than others, creating a narrower spread of shot as it exits. As a result, it is ideal for long-range shooting and precise targeting. Full chokes are commonly used in hunting situations where accuracy and distance are crucial.
Refers to the amount of constriction at the muzzle.

Best guess: You have a shotgun manufactured in Croatia. "Pun" means "Full" in Croatian. "Pola" means "Half". You would have something like 70% constriction in the Pun barrel and 55 to 60% constriction in the Pola barrel.

The Nobel Hayen Model 602J 20 gauge shotgun typically features a fixed choke, often with a cylinder or modified constriction. The specific choke can vary depending on the production year and configuration of the shotgun. To confirm the exact choke type, it's best to refer to the manufacturer's documentation or check the markings on the shotgun itself.
