Correct answer: B. Propyne
- A. Pent-1-yne
- B. Propyne
- C. Ethyne
- D. But-1-yne
Explanation
Propyne is the correct answer as it is commonly used as a rocket fuel. It packs a lot of energy in its triple bond and has no significant health or explosion hazard. Ethyne and But-1-yne are not preferred choices for rocket fuels due to safety concerns or lower energy content.
