As Bookworm83 pointed out already, C nor D couldn't possibly correct, also due to the reason that he was able to come up with the 14 point plan. However, the real answer to your question would be A - he was very shy.
The shyness of Woodrow Wilson has been readily documented in variou sources and is also the reason why it's th ecorrect answer. Overcoming something like shyness was not an easy thing to do for him.
I believe the answer is C. <span>He tended to focus on small issues, and did not look at the larger picture</span>
The correct answer is B) He was more Lenient towards former Confederates than Radical Republicans wanted.
President Johnson was the Vice-President of the United States before being sworn in after the Assassination of President Abraham Lincoln.
After assuming office he followed the path of reconstruction as envisaged by President Lincoln.
He was lenient in the reconstruction era to the dismay of many radical republicans who wanted not only wanted swift action to bring in the Southern States within the Union but were also looking for trials and imprisonment of many Confederate leaders.
For the remaining years of his Presidency, he was locked in a battle with Congress and other Republicans in how to deal with the reconstruction of the union.
