Answer: C

Explanation:

Working plans for dry systems are required to include the total system volume, as this information is critical for determining the amount of air or nitrogen needed to pressurize the system and for calculating the time to water delivery. This requirement helps ensure the system’s effective operation and quick response in the event of a fire.

Reference: NFPA 13 requirements for the documentation and planning of sprinkler systems, emphasizing the importance of detailed system information for dry configurations.
