What document would be used to identify the stock number to circuit symbol in Part 2 of COSAL?

The correct document utilized to identify the stock number corresponding to the circuit symbol in Part 2 of the COSAL (Component of Shipboard Allowances) is Section B. This section is specifically designated for detailing the stock numbers alongside the associated circuit symbols. Section B provides necessary references for shipboard maintenance and logistics personnel, facilitating efficient inventory management and ensuring the correct components are ordered or replaced as needed.

The other sections serve different purposes within the COSAL. Section A typically contains information regarding the basic allowance for the maintenance and operation of systems, while Section C contains information on repair parts for equipment. Section D, on the other hand, usually includes supply support information. Each of these sections has its own function and does not include the stock numbers in conjunction with circuit symbols, which is why Section B is the appropriate answer.
