B. seized Washington and set fire to the presidential mansion.

Explanation:

In August 1814, there ensued a few weeks of war between United State and England troops.

The British troops invaded, seized Washington and burnt the presidential mansion (white house), which was a reprisal attack due to Americas attack on York in Ontario.

The attack by American troops on the city in Canada in 1812 was counted as offensive by British. Thus her attack on Washington D.C, but the American troops surrendered to British without a counter attack which averted the war.
