Solve this multiple-choice question and choose the correct option.

Post-harvest biology: Which gas is used commercially to induce/artificially ripen green fruits? Select the natural plant hormone gas used for ripening. Choose the correct option.

Difficulty: Easy

Ethylene (C₂H₄)
Acetylene (C₂H₂)
Carbon dioxide (CO₂)
Ammonia (NH₃)

Correct Answer: Ethylene (C₂H₄)

Explanation:

ConceptEthylene is a natural plant hormone that promotes ripening; it is used in controlled environments to ripen climacteric fruits. (Acetylene can show ethylene-like effects but ethylene is standard.)

Final AnswerEthylene (C₂H₄)
