The right answer is option b. as we know that battery manufacturing factories use sulphuric acid to manufacture battery whose PH value is very close to zero. as the emmition of such a strong in water even in less quantity enough to make the water acidic. so, when this acid mix with water it's PH down to 3.5 to 4.5 .

Explanation:
The pH scale is a measure of acidity or alkalinity of a solution. It ranges from 0 to 14, with a pH of 7 being neutral. A pH below 7 indicates acidity, while a pH above 7 indicates alkalinity.
In this scenario, the pH of the water sample collected from the river is found to be acidic, ranging from 3.5 to 4.5. This indicates that the water is more acidic than neutral. The question asks which of the given factories is most likely responsible for lowering the pH of the river water.
Soap and detergent factory:
- Soap and detergent factories produce products that are typically alkaline in nature.
- They contain substances such as sodium hydroxide or potassium hydroxide, which can increase the pH of water.
- Therefore, a soap and detergent factory is not the most likely cause for lowering the pH of river water.
Plastic cup manufacturing factory:
- Plastic cup manufacturing factories do not typically produce substances that can significantly alter the pH of water.
- Therefore, a plastic cup manufacturing factory is not the most likely cause for lowering the pH of river water.
Alcohol distillery:
- Alcohol distilleries produce ethanol, which is a weak acid.
- However, the pH of ethanol is typically around 7, which is neutral.
- Therefore, an alcohol distillery is not the most likely cause for lowering the pH of river water.
Lead battery manufacturing factory:
- Lead battery manufacturing factories use sulfuric acid in the production process.
- Sulfuric acid is a strong acid that can significantly lower the pH of water.
- The discharge of effluents containing sulfuric acid from a lead battery manufacturing factory into the river can therefore lower the pH of the river water, making it more acidic.
- This makes the lead battery manufacturing factory the most likely cause for lowering the pH of the river water in this scenario.
Therefore, the correct answer is option 'B' - Lead battery manufacturing factory.
