The correct answer is A. He was arrested on a charge of theft, but was released for lack of evidence.
The other options are incorrect because they do not accurately reflect the sentence. Option B is incorrect because it uses the passive voice, which is not necessary in this sentence. Option C is incorrect because it uses the past participle “released” as an adjective, which is not correct grammar. Option D is incorrect because it is not a complete sentence.
The sentence is about a man who was arrested on the charge of theft. However, he was released because there was not enough evidence to convict him. This means that he was not guilty of the crime.
