b. The President could give asylum to any immigrant he wished.
The Alien and Sedition Acts of 1798, in anticipation of an expected war with France, aimed to restrict the activities of foreign residents in the country, to give the government power to deport foreigners deemed dangerous (Option A), to limit freedom of speech and of the press and allowed the President to imprison whoever openly opposed to their measures (Option C), among others.
The Act focused on restricting measures toward foreigners and American citizens and didn't focus on facilitating the entrance of immigrants in the nation, therefore option b is NOT true.
