Overall, the fluency is best described as
o natural and flowing.
o choppy and incomplete.
loose and unstructured.
inconsistent and unconnected.

Natural and flowing is the correct answer.

Explanation:

Fluency is the quality of speaking in a natural way, meaning that the speaker should not talk so fast (at the point that the speech couldn't be easy to understand) or so slow (which could make the conversation difficult if the audience had to connect phrases that don't seem to be connected.)
