Answer: B.He was a radical who wanted immediate emancipation of all slaves.
Explanation:
In the second and third verses of the first stanza, the poet expresses hatred for the practice of slavery. He then goes on to praise those who show courage by standing up to the tyranny of slavery.
In the second stanza, he challenges the nation to stop being a slumbering nation, that is, ignoring the evils of slavery. These verses:
"...shall hear, the fetter's link be broken" signifies that the poet wanted an emancipation of slaves.
My heart hath leaped to answer thine,
And echo back thy words,
As leaps the warrior's at the shine
And flash of kindred swords!
By the way he identifies with slaves in these verses, it can be inferred that he wanted an immediate freedom of slaves.
