Show answer and solution

Correct answer: C. Ethylene (the 'ripening hormone')

Ethylene (C₂H₄) — only gaseous plant hormone. Triggers fruit ripening (especially climacteric fruits like banana, mango, tomato), leaf abscission, flower senescence. Commercial banana ripening uses ethephon (releases ethylene).
