Explanation:

William Wilberforce was a key figure in the British abolition movement. He was a prominent politician who dedicated much of his life to campaigning for the abolition of the slave trade and later for the abolition of slavery itself in the British Empire. Olaudah Equiano was a formerly enslaved person who became an abolitionist but was more associated with the British abolitionist movement as a writer and speaker rather than a leader in the political - legislative sense like Wilberforce. Frederick Douglass was an American abolitionist. Mary Stewart is not a well - known figure in the British abolition movement.

Answer:

William Wilberforce.
