Awelded, fully hermetic
Bexternal-drive
Copen
Dserviceable, bolted, accessible semi-hermetic
AI Explanation
The correct answer is A) welded, fully hermetic. The illustration GS-RA-41 shows a refrigeration compressor, and a fully hermetic compressor has the drive mechanism, typically an electric motor, fully sealed and welded into the compressor unit. This design is common for small refrigeration systems and ensures a completely sealed, airtight system that requires minimal maintenance. The other options, such as an external-drive, open, or semi-hermetic design, would not match the illustration provided.
