Climacteric fruits are:

Correct option is A

The correct answer is (A) Banana and Mango

Explanation:
• Climacteric fruits are those that can continue to ripen after being harvested. They show a sharp rise in respiration rate and ethylene production during ripening.
• Banana and Mango are classic examples of climacteric fruits. They are often harvested 'green' and ripened during transport or storage using ethylene gas.

Information Booster:
• Non-climacteric fruits do not ripen significantly once removed from the plant and do not show a burst of ethylene production. Examples include Citrus, Grapes, Pineapple, and Strawberry.
• The ripening of climacteric fruits is often accompanied by changes in color (loss of chlorophyll), softening of tissue, and conversion of starch to sugar.

Additional Knowledge:
• Option B & C: Grapes are non-climacteric; they must be harvested when fully ripe on the vine.
• Option D: Citrus is non-climacteric. While Peach is climacteric, the pairing with Citrus makes the option incorrect.
• Other climacteric fruits: Papaya, Guava, Apple, Sapota, and Tomato.
