Answer

To determine how many of the given statements are correct, let's analyze each statement one by one.

### Step 1: Analyze Statement A
**Statement A:** Lipases are commercially used in laundries.

- **Explanation:** Lipases are enzymes that break down lipids (fats). In laundry detergents, lipases are added to help remove stains caused by fatty substances. Therefore, this statement is correct.

### Step 2: Analyze Statement B
**Statement B:** Statins are produced by the action of fungus.

- **Explanation:** Statins are a class of drugs used to lower cholesterol levels in the blood. They are indeed produced by certain fungi, specifically the fungus *Aspergillus*. Thus, this statement is also correct.

### Step 3: Analyze Statement C
**Statement C:** Anaerobic sludge digesters are part of secondary treatment.

- **Explanation:** Anaerobic sludge digesters are used in wastewater treatment processes. They function without oxygen and help in the breakdown of organic matter in sludge. This process is typically considered part of secondary treatment in wastewater management. Therefore, this statement is correct as well.

### Conclusion
After analyzing all three statements:
- Statement A is correct.
- Statement B is correct.
