03103 - basic copper and plastic piping practices 45min what often controls the final choice of piping material for many applications, including fuel gas ailding codes he material cost personal preference building owner

Explanation:

To solve this, we analyze the options for what controls piping material choice:

Step 1: Evaluate "building codes"

Building codes (e.g., plumbing or fuel gas codes) mandate material standards for safety/regulatory compliance. For fuel gas (e.g., natural gas), codes often specify approved materials (e.g., certain plastics or metals) to prevent leaks/explosions.

Step 2: Evaluate "material cost"

Cost is a factor, but safety-critical applications (like fuel gas) prioritize compliance over cost alone. Codes take precedence.

Step 3: Evaluate "personal preference"

Piping for fuel gas is highly regulated; personal preference is irrelevant (safety/legal requirements override).

Step 4: Evaluate "building owner"

While owners may have input, codes (not owner preference) govern safety-critical systems like fuel gas piping.

Answer:

A. building codes (assuming "building codes" is option A; adjust identifier if needed, but the correct reason is building codes control material choice for regulated applications like fuel gas).
