Paraphrasing is a skill absolutely necessary to effective listening.

Restating in one's own words what was said proves the message was genuinely understood.

Hearing is only the physical reception of sound and needs no such active restating.

Speaking loudly concerns delivery volume, not the reception and checking of meaning.

Because listening is the fitting skill, the none choice does not apply.

Paraphrasing turns passive hearing into active, confirmed listening.
