Answer:
He showed the officers a hotel receipt and an airplane ticket as proof of his time in Buenos Aires
Explanation:
The above sentence is a complex sentence.
Complex sentences are known to be sentences that have an independent clause and at least one dependent clause. In such sentences, you will discover that a clause can stand alone and give a full meaning while another clause cannot stand alone and give a full thought.
In the sentence above, you will discover that:
"He showed the officers a hotel receipt..." is an independent clause that can stand alone as a sentence and give a full thought but the other half of the sentence joined by a conjunction, "and" "...an airplane ticket as proof of his time in Buenos Aires" cannot stand alone as a sentence and give full thought.
The other two options are not complex sentences.
