Explanation:

• Type SE cable is mainly for service - entrance applications and not typically for underground installations.
• Type UF (Underground Feeder) cable is specifically designed for underground use. It has a durable outer jacket that can withstand the underground environment.
• While Type THHN in PVC conduit can be used in some underground applications (if installed properly as per code), the question is about a permitted wiring method. Type UF is a more straightforward underground - specific cable.
• Type NM (Romex) is for indoor use and not suitable for underground installations even if in a raceway (as per typical code requirements for underground wiring methods).

B. type UF cable
