The correct option is B Rutherford B. Hayes becoming president.
Henry Clay died in 1852, 25 years before the Compromise of 1877 placed
Rutherford B. Hayes in the White House. Clay did play an important role
in the Missouri Compromise of 1820, which enabled Maine (E) to become a
free state in 1820 and Missouri (A) to become a slave state in 1821.
Clay proposed a reduction in tariff of 1833, which convinced South
Carolina to rescind its nullification ordinance (C). Clay wrote the
Compromise of 1850, which admitted California as a free state (D).
