The storage battery generally used in electric power station is

Options

A. nickel -cadmium battery
B. zinc -carbon battery
C. lead -acid battery
D. none of these.

Explanation

To answer the question about the type of storage battery generally used in electric power stations, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Storage Batteries**:
- Storage batteries are devices that store electrical energy for later use. They can be recharged after being depleted.

2. **Identifying Types of Batteries**:
- There are two main types of batteries: primary cells (non-rechargeable) and secondary cells (rechargeable).

3. **Focus on Electric Power Stations**:
- Electric power stations require batteries that can be recharged, as they need a reliable source of energy storage to manage fluctuations in power supply and demand.

4. **Recognizing Secondary Cells**:
- Since electric power stations use rechargeable batteries, we focus on secondary cells.

5. **Lead Acid Batteries**:
- The most common type of secondary cell used in electric power stations is the lead-acid battery. These batteries are known for their reliability and ability to deliver high surge currents.

6. **Conclusion**:
- Therefore, the storage battery generally used in electric power stations is the lead-acid battery.

### Final Answer:
The storage battery generally used in electric power stations is **Lead Acid Battery**.
