Final answer:
Of all current federal judges, more were appointed by President George W. Bush than by any other president.
Step-by-step explanation:
Of all current federal judges, more were appointed by President George W. Bush than by any other president.
To support this claim, we can look at the appointments of the current Supreme Court Justices. Samuel Alito and Brett Kavanaugh, both current federal judges, were appointed by George W. Bush in 2006 and Donald Trump in 2018, respectively.
This shows that George W. Bush has appointed more federal judges than any other president among the current judges. Therefore, the correct answer is option b. George W. Bush.
