Explanation:
A dependent clause cannot stand alone as a sentence. Like an independent clause, it has a subject and a verb. It may not, however, express a complete thought and may begin with a signal word called a subordinating conjunction.
The summary is the answer.
D. Mom should be capitalized because I believe it is a proper noun.
You can replace the word mom with a person's name. That is not always the case however. For example, I called my mom on my.... If you capitalized mom in this sentence and put a name then it wouldn't make sense because the word my was added. Hopefully this helps and makes sense. Good luck!!!
