## Step 1The problem is asking us to identify the type of black flexible pipe that is commonly used underground to run cold water lines over long distances. The options provided are Copper, Polyethylene, PVC, and Steel.## Step 2Copper is a good conductor of electricity and is not flexible. It is also expensive and can be corroded by water over time.## Step 3Polyethylene is a type of plastic that is flexible, durable, and resistant to corrosion. It is also cost-effective and can withstand high pressure.## Step 4PVC (Polyvinyl Chloride) is a type of plastic that is not flexible and can be brittle. It is also not suitable for high-pressure applications.## Step 5Steel is a strong and durable material, but it is not flexible and can be expensive.## Step 6Considering the properties of each material, Polyethylene is the most suitable choice for running cold water lines over long distances underground. It is flexible, durable, resistant to corrosion, cost-effective, and can withstand high pressure.
