As compared to cast iron pipes, steel pipes are A. Heavier B. Stronger C. Costlier D. Less susceptible to corrosion

The correct answer is: B. Stronger

Cast iron pipes are made of a brittle material that is prone to cracking and breaking. Steel pipes, on the other hand, are made of a strong and ductile material that can withstand more stress and strain. This makes steel pipes a better choice for applications where strength is important, such as in high-pressure pipelines.

Here is a brief explanation of each option:

• A. Heavier – Steel pipes are heavier than cast iron pipes because they are made of a denser material. However, this difference in weight is not usually significant for most applications.
• C. Costlier – Steel pipes are typically more expensive than cast iron pipes. This is because steel is a more expensive material than cast iron. However, the higher cost of steel pipes is often offset by their longer lifespan and lower maintenance costs.
• D. Less susceptible to corrosion – Steel pipes are less susceptible to corrosion than cast iron pipes. This is because steel is a more corrosion-resistant material than cast iron. However, both steel and cast iron pipes can corrode if they are not properly protected.
