    C4 plants utilize the Hatch and Slack pathway for carbon fixation, which allows them to thrive in hot and dry climates. Among the following, which plant is categorized as a C4 plant?

    A Rice Correct Answer Incorrect Answer
    B Wheat Correct Answer Incorrect Answer
    C Mango Correct Answer Incorrect Answer
    D Pineapple Correct Answer Incorrect Answer
    E Grapes Correct Answer Incorrect Answer

    Solution

    C4 plants, like pineapple, use the Hatch and Slack pathway to fix carbon more efficiently in high-temperature environments. This adaptation helps reduce photorespiration and enhances growth in arid conditions, unlike C3 plants such as rice and wheat, which use the Calvin cycle.
