Question

Explanation:

Enharmonic notes are defined as musical notes that are sounded at the same pitch level but are referred to by different names (for example, C# and Db). The other options refer to staccato (short and detached), a pitch alteration, and a musical extension, which are unrelated to the definition of enharmonic notes.
