AI Explanation
The correct answer is D. The illustration GS-RA-69 shows a hermetic service valve, which is used to gain access to a hermetic (sealed) system. This type of valve features a Schrader core valve that is unseated by the core depressor of a hose fitting when it is attached. This allows access to the sealed system for service or maintenance. The other options, A, B, and C, do not match the description of a hermetic service valve with a Schrader core valve. They likely represent different types of valves or fittings used in other applications.
