Which sentence contains an essential adjective clause? the sponsor who pays for our uniforms deserves advertising at each game. our sponsors, who fund the team, are invited to the opening game. after explaining the sponsorship levels, they agreed to join at the silver level. during halftime, the speaker announced the sponsors.

The correct answer is - The sponsor who pays for our uniforms deserves advertising at each game.

An essential phrase, as the name itself suggests, is really important and cannot be excluded from a sentence, unlike a non-essential phrase. Essential phrases, unlike non-essential ones, are never set off from the rest of the sentence by commas. As you can see, the only sentence that does doesn't do that is sentence 1, which is why it is the correct answer here.
