A sentence has been given in Active voice. Out of the four alternatives suggested below, select the one which best expresses the same sentence in Passive voice. 
 

We will have selected a new team by the weekend. 

A new team will have been selected by us by the weekend.

A new team will have been selected by us by the weekend.

Explanation:

• By the weekend a new team will have been selected by us.: This passive construction reverses the word order and correctly forms the passive voice, but it places "by the weekend" at the beginning, which disrupts the natural flow of the sentence.
• A new team will have been selected by us by the weekend.: This passive construction is the most accurate and maintains the original word order while correctly expressing the same meaning in the passive voice.
• A new team will have selected by us by the weekend.: This active construction maintains the original word order but is not grammatically correct, as it should be "will have been selected" in the passive voice.
• A new team will have been selected by us.: This passive construction correctly forms the passive voice and maintains the original time frame, making it the most appropriate option.
