Answer: A: more
Explanation:
- the sentence: "The second hotel room had more storage than the first one." is grammatically correct
- if the phrase "the most" was used in this sentence: "The second hotel room had the most storage than the first one." it just sounds odd
- for example, one of the correct ways to use it would be "Out of the two hotel rooms, the second one had the most storage."
- if the word "morer" was used in this sentence: "The second hotel room had morer storage than the first one." it also sounds wrong. In addition, morer isn't a word so it is never grammatically correct
