Final answer:
Olaudah Equiano most likely did not experience contentment considering his traumatic circumstances as a slave; thus the correct option is C. Content.
Step-by-step explanation:
The student is asking about the feelings experienced by Olaudah Equiano, an African man who was sold into slavery and later wrote about his experiences.
The feelings mentioned in the options: horror, anguish, and despair are all negative emotions that align with the experiences of a person who has been through immense suffering and trauma as a slave.
However, contentment is a positive emotion and is not associated with the dire circumstances described in Equiano's narratives or the other text references provided.
Therefore, the correct option is C. Content, as it is not a feeling Equiano would likely have experienced given the context of the distressing situations he and others in bondage endured.
