D Correct answer
Explanation

The original sentence has a grammatical error - it lacks proper verb structure and tense consistency. Option D corrects this by using "is supplied" as the main verb phrase, properly modifying the subject "natural gas." The appositive phrase "the United States' second biggest fuel source after crude oil" is correctly placed between commas. This creates a grammatically complete and coherent sentence.
