Question

happiness. here was a time, in which your tender feelings for yourselves had engaged you thus to declare, you were then impressed with proper ideas of the great violation of liberty, and the free possession of those blessings, to which you were entitled by nature; but, sir, how pitiable is it to reflect, that although you were so fully convinced of the benevolence of the father of mankind, and of his equal and impartial distribution of these rights and privileges, which he hath conferred upon them, that you should at the same time counteract his mercies, in detaining by fraud and violence so numerous a part of my brethren under groaning captivity and cruel oppression, that you should at the same time be found guilty of that most criminal act, which you professedly detested in others, with respect to yourselves. (50 - 51)

benjamin banneker points out that liberty is the peculiar blessing of heaven

Explanation:

Benjamin Banneker's text criticizes the contradiction of claiming liberty while oppressing others. He extends the concept of liberty from the Declaration (which was initially more limited in its application in practice, often excluding Black people) to include all people, especially those "under groaning captivity and cruel oppression." The first option is incorrect as it misrepresents his view (he is against such oppression). The third option is wrong as liberty isn't about doing whatever one wants without consequences. The fourth option is too vague and not in line with the text's argument about inclusion of the oppressed in the concept of liberty.

Answer:

Benjamin Banneker takes the words of the Declaration, and extends liberty to include all people, including those currently "under groaning captivity and cruel oppression."
