Answer

The option that removes the subordinating conjunction to form a complete independent sentence.
The correct option removes the subordinating conjunction to turn the dependent clause into a complete, independent sentence with its own subject and verb. This resolves the sentence fragment error while maintaining the intended meaning.

Step-by-Step Solution

1
Identify the grammatical error in the underlined portion.
The clause starting with the subordinating conjunction is treated as a standalone sentence, making it a dependent clause fragment.
A dependent clause cannot stand alone as a grammatically complete sentence.
2
Evaluate the choices to find one that resolves the fragment without introducing new punctuation errors.
The revision that removes the subordinating conjunction creates a complete, independent sentence.
An independent sentence must express a complete thought and contain both a subject and a verb.
