Question

On the basis of ripening behaviour, choose the non climacteric fruits
(A). Litchi
(B). Grape
(C). Jackfruit
(D). Pineapple
Choose the correct answer from the options given below:

• A. (A), (B) and (D) only.
• B. (A), (B) and (C) only.
• C. (A), (B), (C) and (D).
• D. (B), (C) and (D) only.

Hint:

A simple rule of thumb for exams: If a fruit needs to be bought when it's already ripe and won't get better on your kitchen counter (like berries, citrus, grapes), it's likely non-climacteric. If you can buy it green and it will ripen (like bananas, avocados, mangoes), it's climacteric.

Answer 1

The Correct Option is A

Step 1: Introduction:
Fruits are categorized by their ripening behavior: \[\begin{array}{rl} \bullet & \text{Climacteric fruits: Ripen after harvest, with increased respiration and ethylene production. Examples: bananas, mangoes, apples.} \\ \bullet & \text{Non-climacteric fruits: Do not ripen after harvest; picked ripe. No respiration or ethylene peak. Examples: citrus fruits, grapes, strawberries.} \\ \end{array}\] The question seeks to identify non-climacteric fruits from a list.

Step 2: Fruit Classification:
Let's classify each fruit:
\[\begin{array}{rl} \bullet & \text{(A) Litchi: Non-climacteric. Quality declines post-harvest. } \\ \bullet & \text{(B) Grape: Non-climacteric. Must be harvested ripe. } \\ \bullet & \text{(C) Jackfruit: Climacteric. Ripens and softens after harvest. } \\ \bullet & \text{(D) Pineapple: Non-climacteric. Slight color change, but no ripening after harvest. } \\ \end{array}\] Therefore, Litchi, Grape, and Pineapple are non-climacteric.

Step 3: Answer:
The non-climacteric fruits are (A) Litchi, (B) Grape, and (D) Pineapple. This corresponds to options (A), (B), and (D).
