Question

1. what is a valid fair use of a popular song that’s just come out?

use of the full song within a critique on the radio
use of a small portion of the song in an online class presentation
use of a small portion of the song as the background for a perfume ad on tv
use of the full song for a new web page for a start - up landscaping business

Explanation:

Fair use typically allows limited use of copyrighted material for purposes like criticism, commentary, teaching, etc. Using a small portion of a song in an online class presentation (for educational purposes) fits fair use. Using the full song for a business (landscaping or perfume ad) or full song in radio critique (full use without proper fair use context for critique likely isn't fair; fair use for critique usually uses small portions) doesn't align. So the valid fair use is using a small portion in an online class presentation.

Answer:

C. use of a small portion of the song in an online class presentation (assuming the options are labeled A - D with the third option as C; if original labels differ, adjust, but based on the order: the third option "use of a small portion of the song in an online class presentation" is the valid one)
