Attorney Frank, licensed in State F, is a solo practitioner. He hires a new paralegal, Sarah, who previously worked for another law firm where she gained extensive experience drafting pleadings and interviewing witnesses. Frank instructs Sarah to draft a complex motion for summary judgment, assuring her that he will 'review it thoroughly before filing.' However, due to an urgent client matter, Frank quickly skims the motion, makes minor formatting changes, and files it without fully verifying its legal arguments or factual accuracy. The motion is subsequently denied due to significant legal deficiencies. Is Frank subject to disciplinary action?

1. AYes, but only if Sarah was not officially certified as a paralegal, as supervision is only required for uncertified staff.
2. BNo, because Frank delegated the drafting to an experienced paralegal, and paralegals are expected to perform such tasks.
3. CNo, because he did review the motion, albeit briefly, and the ultimate responsibility lies with the paralegal for the drafting.
4. DYes, because he failed to adequately supervise Sarah and ensure the work product conformed to professional standards.
