The correct Answer is:
To determine which statements are correct, let's analyze each one step by step: ### Step 1: Analyze Statement A **Statement A:** Water logging results in soil salinity. - **Explanation:** Water logging occurs when there is an excessive accumulation of water in the soil. This can prevent the leaching of salts that are brought into the soil through irrigation. As a result, salts accumulate in the soil, leading to increased salinity. - **Conclusion:** This statement is **correct**. ### Step 2: Analyze Statement B **Statement B:** UV rays are essential for production as well as degradation of ozone. - **Explanation:** Ultraviolet (UV) rays from the sun play a crucial role in the formation of ozone in the stratosphere. They also contribute to the breakdown of ozone molecules. Therefore, UV rays are indeed involved in both the production and degradation of ozone. - **Conclusion:** This statement is **correct**. ### Step 3: Analyze Statement C **Statement C:** There are working Eco-San in many areas of Kerala and Sri Lanka. - **Explanation:** Eco-San (Ecological Sanitation) refers to sustainable sanitation systems that recycle nutrients from human waste. There are indeed operational Eco-San systems in various regions of Kerala and Sri Lanka, promoting hygienic and efficient waste disposal. - **Conclusion:** This statement is **correct**. ### Step 4: Analyze Statement D **Statement D:** Accelerated Eutrophication is generally anthropogenic. - **Explanation:** Accelerated eutrophication refers to the rapid increase in nutrient levels (particularly nitrogen and phosphorus) in water bodies, often due to human activities such as agricultural runoff, sewage discharge, and industrial waste. This process is indeed primarily driven by human actions. - **Conclusion:** This statement is **correct**. ### Final Conclusion Since all four statements (A, B, C, and D) are correct, the correct option is: **Correct Option:** All statements are correct. ---
