AI Explanation
The correct answer is D. The valve described in the question, which features a Schrader core valve that is unseated by the core depressor of a hose fitting when attached, is commonly referred to as a Schrader valve. This type of valve is used to gain access to hermetic systems, such as refrigeration and air conditioning systems, in order to charge, evacuate, or test the system. The other answer choices (A, B, and C) do not specifically describe a Schrader valve, and therefore are not the correct answer to the question.
