BB
CC
DD
AI Explanation
The correct answer is D. The illustration GS-RA-03 shows the correct hand valve configuration for monitoring both the low and high system pressures. Option D depicts the proper set-up, with the low-pressure gauge connected to the low-pressure port and the high-pressure gauge connected to the high-pressure port. This configuration allows the operator to independently monitor the pressures in both the low and high-pressure systems, which is a critical safety requirement for the proper functioning and maintenance of the overall system. The other options (A, B, and C) do not provide this dual pressure monitoring capability.
