Step-by-step explanation:
The correct answer to the question 'Posturing codes, or P codes, indicate unit type code (UTC) records are generally available?' is b) B codes. Posturing codes are used within the military logistics system to indicate the status of unit type codes (UTCs), which are records of the composition, capability, and requirements of a unit. These codes are vital for military planning and readiness. B codes are used to show that UTCs are available without restrictions, meaning they are ready to deploy. This detail is critical for personnel tasked with overseeing unit preparedness and deployment.
