Helps fruit ripen
A
Auxin
B
Gibberellin
C
Cytokinins
D
Ethylene
Explanation: 

Detailed explanation-1: -Ethylene is an important plant hormone. In bananas and many other fruits, production of ethylene surges when the fruit is ready to ripen. This surge triggers the transformation of a hard, green, dull fruit into a tender, gaudy, sweet thing that’s ready-to-eat.

Detailed explanation-2: -The key here is ethylene. Ethylene is a natural gas given off by fruit that helps in ripening. To speed things up even faster, we recommend adding in an apple or banana! These fruits give off more ethylene than other fruits and will really aid in moving the ripening process along!

Detailed explanation-3: -Fruits that respond to ethylene are called “climacteric” and include apples, avocados, bananas, figs, mangoes, papayas, peaches, pears and tomatoes. These fruits exhibit a burst in respiration (basically, heavy breathing, called the “climacteric rise”) along with a spike in ethylene production as they ripen.

Detailed explanation-4: -External application of ethylene gas generated from various sources such as ethylene gas cylinders, compressed ethylene gas, ethanol, ethephon, etc. can be used on fruits to trigger the ripening process in fruits. Any source of ethylene gas coming in direct contact with fruits is not permitted.
