The correct answer is C. Dante's view of traitors as the worst of a sinner is evident when he shows that they reside in the final ring of Hell. Inferno is the first part of Italian writer Dante Alighieri's 14th-century epic poem Divine Comedy. The Inferno tells the journey of Dante through Hell, guided by the ancient Roman poet Virgil. As an allegory, the Divine Comedy represents the journey of the soul towards God, with the hell that describes the recognition and rejection of sin.
I believe the answer is: B. the shooting of an unarmed rider.
In the speech, there is a dark connotation that made by the speaker when he mentioned the shooting of unarmed riders who are not willing to conform to their orders. Especially to the lower ranks who are bound by the orders from higher officers.
