Hey there,
I assume there was a sentence to go along with this question, but you have not provided that to us, but I can try my best to help you out here. You ask what word can replace the word "cheap" positively, A. is the only one that makes a non-negative image for this character Mr. Larson.
If I am incorrect, please let me know! I'd love to further improve my knowledge.
xoxo, Ash.
