The answer is a syllable within a word.

Explanation:

A memory aid, or mnemonic, is a tecnique used to trigger a memory by means of visualization, rhyme, etc. In here, the word "end" is included in the word "friend", which creates a rhyme that makes the sentence easier to remember.

I believe the correct answer is the first one: a syllabe within a word.
