Answer:
The rhetorical appeal found in the excerpt is:
C. pathos, because it appeal to audience's feelings of unity and patriotism.
Step-by-step explanation:
What Churchill is basically saying in the passage is that England will not surrender. That the English people will keep on fighting, even if other countries are being defeated. He does not talk of himself and his qualifications as a leader. He does not explain military tactics or preparations. In this passage, he does not present an argument against Germany. All he does is appeal to his audience's emotions. He makes use of repetition quite efficiently to do so: "We shall". He does not say "I", or "you", it's always "we", helping create a sense of unity. He speaks of strength, of confidence, of endurance and resilience. Having that in mind, the best option is letter C. pathos, because it appeal to audience's feelings of unity and patriotism.
