Correct answer: C. To break down large hydrocarbon molecules into smaller, more valuable ones

  • A. To remove sulfur from gasoline
  • B. To increase the octane number of gasoline
  • C. To break down large hydrocarbon molecules into smaller, more valuable ones
  • D. To combine small hydrocarbon molecules into larger ones

Explanation

Catalytic cracking uses heat, pressure, and a catalyst to break large, less useful hydrocarbon chains from crude oil into smaller, more valuable molecules. This process is essential for increasing the supply of gasoline.
