AI Explanation
The correct answer is C. The illustration GS-RA-50 shows the proper method of attaching a TXV feeler bulb to a large line (7/8" and larger) with a horizontal run. Option C, which depicts securing the feeler bulb with a metal clamp, is the correct method as it ensures the bulb is in direct contact with the refrigerant line, allowing for accurate temperature sensing and proper expansion valve operation. The other options, A, B, and D, are incorrect as they do not provide the necessary secure and direct contact between the feeler bulb and the refrigerant line, which is essential for the TXV to function properly.
