OFFICIAL EXPLANATION:
The main error in the sentence concerns subject-verb agreement. The singular subject, price, requires a singular verb. Additionally, the underlined portion is needlessly wordy. First, eliminate answer choices that don’t correct the agreement problem. Then, focus on choices that clarify the language.
Both Choices (B) and (C) perpetuate the agreement problem by providing plural verbs for the singular subject. Eliminate those along with Choice (A), and you’re left with Choices (D) and (E).
Choice (E) is constructed even more awkwardly than the original sentence, so
Choice (D) is the best answer: Recently, the price of crude oil has fluctuated with the demand for gasoline in China
