Which of the following is NOT a climacteric fruit based on the given examples?

Explanation:
Ripening behavior after harvest is the key idea here: climacteric fruits exhibit a burst in respiration and a rise in ethylene production as they ripen, which allows them to continue ripening after being picked. Tomatoes, bananas, and mangoes all show this pattern, becoming softer, sweeter, and often changing color once picked thanks to the ethylene-driven ripening process. Pineapple does not show this postharvest ripening surge; its ripening is not strongly ethylene-driven and it doesn’t continue to ripen significantly after harvest. So pineapple is not a climacteric fruit.
