• A. Decrease in flower abscission
• B. Decreases in femaleness
• C. Increase in fruit ripening
• D. Increase in cell elongation

Answer 1

The correct option is C Increase in fruit ripening

Ethylene is a gaseous plant hormone. It is also called as ripening hormone as it increases ripening of fruits. Fruit ripening is accompanied by increase rate of respiration. Due to increased respiration, complex carbohydrates are broken down into simpler sugars and cell wall becomes soft. It inhibits cell division. It is also involved in abscission of leaves, fruits and flowers.
