Answer: D) repeated words.
Explanation: In the given paragraph, we can see the description of how the speaker used to spend (and enjoy) his summer vacations at a cabin. The major fault of the paragraph is the repeated words, the speaker repeats the word "summer" and also "summer vacations" too many times ("During our summer vacations," "These summer vacations were always fun,"All summer, we would take hikes," " Summer smells, summer flowers," "these are my memories of summer vacations"), to correct this fault the speaker should combine sentences using conjunctions or conjunctive adverbs to avoid repetition.
