The evidence in chapter 20 that Mr. Collins has no real feelings for Elizabeth is option C: He is easily swayed by the opinions of others. The text describes Mr. Collins's demeanor after Elizabeth's rejection as exhibiting a stiffness of manner and resentful silence, suggesting that his interest in her was not borne of deep affection but rather the convenience and practicality of the match. Mr. Collins's feelings do not seem deeply hurt, and there is no mention of a heartfelt love letter, jealousy over other men, or respect for her feelings, which might have indicated a stronger attachment.
