Answer: B Susana thought that the shorter plant looked better in the living room
Step-by-step explanation:
Comparative comparison is when you are comparing two nouns, and using adjectives to compare them better. In this case, they are comparing more than one tree meaning that the word isn't positive, rather, it is comparative. Examples of these are larger, angrier, smaller, weirder, etc. Susana thought that the shorter plant looked better in the living room. Though A is still a correct sentence, it isn't grammatically accurate this comparison. Therefore, B is the answer.
