Explanation:

Effluents from certain industries can significantly impact the pH levels of river water, causing acidification:

- Lead battery manufacturing industries: These industries often release acidic effluents, which can lower the pH of river water. Acidic waste, including sulfuric acid used in batteries, contributes to a decrease in pH, increasing the acidity of the water.

- Alcohol distillery industries, plastic cup manufacturing industries, and soap and detergent industries have effluents that may affect water quality, but they are not typically known for specifically lowering pH levels as much as lead battery manufacturing.

Answer: Option 4 - Lead battery manufacturing industries
