<p>The correct answer is <strong>(D) are being performed</strong>.</p><p style="">So, the sentence would read: "The region managers meet regularly with the staff to ensure that procedures are being performed correctly."</p><p style="">In this context:</p><p style="">(A) "to be performed" suggests a future intention or purpose, which isn't the main focus of this sentence.</p><p style="">(B) "would have performed" implies a condition in the past that did not happen, which doesn't fit the context of the sentence.</p><p style="">(C) "had been performed" is the past perfect passive form. It would suggest the action was completed in the past before some other past event, which isn't the case here.</p><p style="">(D) "are being performed" is in the present continuous passive form. It indicates an ongoing action in the present, which fits perfectly in this context, where the managers want to ensure that procedures are currently (and continually) being carried out correctly.</p>
