Answer:
B. always using short, choppy sentences
Explanation:
Using short and choppy sentences can make your writing appear unsophisticated and your ideas seem disconnected. One can use a modifying phrase to reduce the usage of short and choppy sentences
e.g I was exhausted. I stared at the page. I was unable to comprehend a single word. can be well written as
Exhausted, I stared at the page, unable to comprehend a single word.
you can as well try starting your sentences with simple subject, a
prepositional phrase, a dependent clause, a modifying phrase, etc.
