In an aircraft with a reciprocating engine, what information must be located near the fuel tank filler opening?

Explanation:
For a reciprocating-engine aircraft, you must clearly label the fuel type and the minimum acceptable grade near the filler opening. That labeling prevents misfueling and ensures the correct octane rating is used, which is essential for proper engine performance and to avoid damage. The required label indicates AVGAS and the minimum grade (such as 100LL or the specific grade specified by the manufacturer). The others are not appropriate because Jet Fuel is for turbine engines, and omitting the grade or using the wrong fuel term can lead to selecting an incorrect fuel.
