Select the most appropriate option to fill in the blank and make a grammatically correct sentence.

The players returned to the dilapidated hotel that _____ them.

was allocated to

The most appropriate option to fill in the blank is was allocated to.

The sentence is in the past tense, and the verb "allocate" needs a past tense form. The past tense form of "allocate" is "allocated." The sentence is also in the passive voice, which means that the players are the recipients of the action of allocating.

The other options are not as appropriate.

• Was been allocated to is grammatically incorrect. The past participle of the verb "allocate" is "allocated," not "been allocated."
• Were allocated to is also grammatically incorrect. The verb "allocate" needs to agree with the subject of the sentence, which is "players." In this case, the verb should be plural, "were allocated."
• Had allocated to is grammatically correct, but it does not make sense in the context of the sentence. The sentence is about the players returning to the hotel that was allocated to them. The verb "had allocated" would be used if the players were returning to the hotel after it had been allocated to them in the past. However, in this sentence, the allocation of the hotel to the players is happening at the same time as their return to the hotel.
