Answer Details

The best option to complete the sentence is "was being." This is because the sentence is in the past tense, and the action of arranging the hall was already in progress when "we" arrived. The phrase "was being" is in the past continuous tense, which is used to describe an action that was ongoing in the past. Option A, "has been," is in the present perfect tense and suggests that the hall is still being arranged, which does not fit the context of the sentence. Option B, "is being," is in the present continuous tense and suggests that the hall is currently being arranged, which again does not fit the past tense context of the sentence. Option D, "had been," is in the past perfect tense and suggests that the arranging of the hall was already completed before "we" arrived, which also does not fit the context of the sentence.
