The correct answer is D. As president, John Tyler vetoed a bill to create a new national bank, thus angering Whigs.

Explanation:

John Tyler assumed office after the sudden death of President William Henry Harrison. He did not know how to be consistent with the ideals of his party (the Whig Party), since he was raised in the aristocratic environment of Virginia. He did not promote any of the campaign reforms and his southern attitude contributed to the regionalist and secessionist sentiment of the slave states. This attitude brought him closer to the Democratic Party, refusing to relaunch a third National Bank and not preventing the rise in customs tariffs.

Annoyed by the image of interim president that his own party assigned him, Tyler began his term facing Whig leaders for his rejection of the National Bank. His stubbornness on this issue, probably motivated by his desire to reaffirm his authority against his party, led to the block resignation of his entire cabinet, which he had inherited from Harrison, with the sole exception of Secretary of State Daniel Webster. Although his veto to the National Bank diluted any possibility of restitution of the relations with the Whig Party, Tyler himself was also harmed by this crisis as he lost political support.

the answer is option a.
