Answer

Brief Explanations:

Balance Valves/Flow Meters help in regulating and measuring flow for maintenance. Shutoff Valves allow isolation of parts of the system. Purge Valves and Air Bleeders are used to remove air and unwanted substances. All these components make system - maintenance easier on pre - made manifolds.

Answer:

D. All of these
