The correct Answer is:
To solve the matching question, we will analyze each item in List I and find the corresponding effect from List II. ### Step-by-Step Solution: 1. **Analyze A) `NO_(3)^(-)` ion in drinking water greater than 50 ppm:** - The maximum limit of nitrate (NO3-) in drinking water is 50 ppm. When it exceeds this limit, it can cause a condition known as **Blue Baby Syndrome** (Methemoglobinemia), which affects infants and leads to a decrease in the amount of oxygen carried in the blood, causing a blue discoloration of the skin. - **Match:** A → IV (Blue Baby Syndrome) 2. **Analyze B) `SO_(4)^(2-)` ion greater than 500 ppm:** - The sulfate ion (SO4^2-) is considered safe up to 500 ppm. When the concentration exceeds this level, it can lead to a **laxative effect**, which includes symptoms like diarrhea and stomach cramps. - **Match:** B → III (Laxative effect) 3. **Analyze C) Mercury poison:** - Mercury poisoning can lead to **Minamata disease**, which is a severe neurological condition caused by the consumption of fish contaminated with methylmercury. This disease is named after Minamata Bay in Japan, where industrial discharge led to severe mercury contamination. - **Match:** C → II (Minamata disease) 4. **Analyze D) Domestic sewage:** - Domestic sewage contributes to the depletion of dissolved oxygen in water bodies. The decomposition of organic matter in sewage consumes oxygen, leading to a reduction in the oxygen available for aquatic life. - **Match:** D → I (Depletion of dissolved oxygen) ### Final Matches: - A → IV (Blue Baby Syndrome) - B → III (Laxative effect) - C → II (Minamata disease) - D → I (Depletion of dissolved oxygen)
