Hi !
We would say: Valentin lui offre des fleurs.
Hello!
The key here is formal v. informal. Célèbres is informal, while <span>célébrez is formal. The phrase in question uses tu which is the informal version of "you", vous being the formal version.
The correct verb for tu is </span><span>célèbres. The answer is a.
Hope this helps!</span>
