    Correct answer: C

    Statement 1 is correct: Prevention of soil runoff IWDP promotes practices that reduce soil erosion, protecting valuable topsoil and improving land fertility.

    Statement 2 is incorrect: Linking perennial and seasonal rivers While water resource management is a part of IWDP, it doesn't focus on physically linking separate river systems. The National River Linking Project is a separate project to interlink rivers.

    Statement 3 is correct: Rainwater harvesting and groundwater recharge IWDP encourages rainwater conservation techniques, allowing more water to infiltrate the ground and replenish aquifers.

    Statement 4 is correct: Regeneration of natural vegetation IWDP often involves planting trees and promoting sustainable land management practices, leading to increased vegetation cover.

    4. D1, 2, 3 and 4
    Answer and explanation

    Correct answer: C

    Statement 1 is correct: Volcanic action releases carbon dioxide trapped within the Earth's crust and mantle.

    Statement 2 is correct: Respiration releases carbon dioxide as a byproduct of cellular respiration in living organisms.

    Statement 3 is incorrect: Photosynthesis removes carbon dioxide from the atmosphere. Plants and other photosynthetic organisms use carbon dioxide during photosynthesis to create organic molecules.

    Statement 4 is correct: The decay of organic matter releases carbon dioxide as decomposers break down dead plants and animals. This process returns carbon stored in organic matter back to the atmosphere as carbon dioxide.
