Answer:
D. Suspend freedom of the press by insisting that editors avoid publishing anti-Union articles or editorials
Step-by-step explanation:
Abraham Lincoln was the 16th president of US. He was the first member of the republican party to become president. Civil war was one of the major events during his presidency.
He had to handle both the military and political aspects of the civil war, Since president was the commander-in-chief during those days, he suspended habeas corpus right in Maryland to weakened the confederate sympathisers.
He also meticulously selected General Ulysses S. Grant to the war in Western Theatre. He issued Emancipation Proclamation in 1863 and freed more than 100,000 blacks. Newly freed slaves served in the Union army and helped the union to win the war as the black soldiers increased the size of union army.
He also issued the proclamation for the blockade to prevent the supply of weapons, supplies and goods to prevent south from gaining foreign aid. He later called a special session of congress and explained that nothing was done that way against the constitution.
But he didn't suspend the freedom of press by insisting tht editors avoid publishing anti-Union articles or editorials.
