Choose the option that best completes the gap(s). The police claim that a number of stolen cars _____ recovered?

Answer Details

The correct option to complete the sentence is "have been". This is because the subject "a number of stolen cars" is plural, so it requires a plural verb "have been". "Has been" is incorrect because it is singular and does not agree in number with the subject. "Has being" is also incorrect because "being" is not used after the auxiliary verb "has".
