Consider the toll owing statements:Steam turbines are suitable for use...
Explanation:
Steam turbines are widely used as prime movers for large steam power plants because of their high efficiency, reliability, and ease of operation. The following are the reasons why steam turbines are considered suitable for large steam power plants:

1. High Capacity: A single steam turbine can be designed for a capacity of 1000 MW or more, making it ideal for use in large steam power plants.

2. Higher Speed: Steam turbines can operate at much higher speeds than reciprocating engines, making them suitable for use in power plants where high output and efficiency are required.

3. Compact Design: Compared to gas turbine power plants, steam turbine power plants are more compact, making them ideal for use in locations where space is limited.

4. Low Maintenance Cost: The maintenance cost and running cost of steam turbines may not increase with years of service, making them a cost-effective option for large steam power plants.

Therefore, the correct answer is option 'C', which includes statements 1, 2, and 4.
