The correct answer is A. 51234.
The first option, “have”, is the verb of the sentence. The second option, “arrested”, is the past participle of the verb “arrest”. The third option, “thieves”, is the direct object of the verb “arrest”. The fourth option, “police”, is the subject of the sentence. The fifth option, “the”, is the article that comes before the noun “police”.
The sentence can be paraphrased as “The police have arrested the thieves.”
Option B, 42513, is incorrect because the past participle “arrested” comes before the direct object “thieves”.
Option C, 52431, is incorrect because the subject “police” comes after the verb “have arrested”.
Option D, 41253, is incorrect because the article “the” comes before the noun “police”.
