How does Rainsford’s opinion on animals change throughout the story?

A
At first, Rainsford believes only humans can feel, but by the end, he agrees with Whitney that animals can also feel “fear of pain” ( Paragraph 13).
B
At first, Rainsford thinks that there is only one rational animal, humans, but then he discovers the new animal that Zaroff has “invented” ( Paragraph 100).
C
At first, Rainsford believes humans are smarter than animals, but then he sees that some humans are actually “a very inferior lot” ( Paragraph 131).
D
At first, Rainsford sees animals only as prizes for human hunters, but later Rainsford sympathizes with the animal “at bay” when he too becomes the hunted ( Paragraph 204).
