Read the excerpt from Thoughts and Sentiments.

It is therefore manifest, that something else ought yet to be done; and what is required, is evidently the incumbent duty of all men of enlightened understanding, and of every man that has any claim or affinity to the name of Christian, that the base treatment which the African Slaves undergo, ought to be abolished; and it is moreover evident, that the whole, or any part of that iniquitous traffic of slavery, can no where, or in any degree, be admitted, but among those who must eventually resign their own claim to any degree of sensibility and humanity, for that of barbarians.

What text detail from this excerpt directly supports Cugoano’s belief that all good Christians have to participate in the abolishment of slavery?

A.“is evidently the incumbent duty of all men of enlightened understanding”
B.“and of every man that has any claim or affinity to the name of Christian”
C.“iniquitous traffic of slavery, can no where, or in any degree, be admitted”
D.“who must eventually resign their own claim to any degree of sensibility”

"Thoughts and Sentiments" was a book written by Ottobah Cugoano and published in 1787, in this document the author directly attacked slavery and support the idea of abolishing it, because of this in this book Cugoano encourages slaves to scape and other people to do actions to stop slavery. This can be seen in the excerpt presented in which the author invites people to take actions against slavery "is evidently the incumbent duty of all men of enlightened understanding" and especially invites Christians to take a position about this issue "and of every man that has any claim or affinity to the name of Christian", this includes not only slavery but the traffic of slaves "any part of that iniquitous traffic of slavery, can nowhere, or in any degree, be admitted".

Considering this it can be concluded, the detail that directly supports Cugoano's belief that all good Christians have to participate in the abolishment of slavery is "and of every man that has any claim or affinity to the name of Christian”, because in this section Cugoano directly addresses Christians to take actions against slavery.
