I believe the correct answer is “All of his neighbors had wells, and a King resented not having one”.
In the first passage from the fairy tale “I Wonder” retold by Lars Cyftman, the sentence that best represents King’s jealous nature is the sentence: “All of his neighbors had wells, and a King resented not having one”, in which his jealousy is clearly stated because King covets what his neighbors have, which is amplified by the verb resent which suggests his feel of bitterness or indignation at them.
