The correct option is C French Revolution
A hierarchical
system of land use and patronage that dominated Europe between the 9th and 14th
centuries is known as feudalism. Under Feudalism, a monarch’s kingdom was
divided and subdivided into agricultural estates called manors. The nobles who
controlled these manors oversaw agricultural production and swore loyalty to
the king. It produced social inequality. But, the French Revolution led to the
end of feudalism with bringing a constitutional monarchy and later a republic.
