Final answer:
Job time records (A) are the documents that track employee start and stop times for the purpose of allocating payroll costs to work in process, unlike attendance time records, payroll contribution notices, or wage and tax forms.
Step-by-step explanation:
The documentation that shows start and stop times with the purpose of allowing the distribution of payroll costs to work in process is (A) job time records. These records specifically track the amount of time an employee spends on different jobs or tasks, which then informs how payroll costs are allocated appropriately to various work in process. This contrasts with (B) attendance time records, which generally only document the presence of employees at work rather than the specifics of their job duties. Options (C) payroll contribution notice and (D) wage and tax forms are more focused on the reporting and documentation of payroll-related contributions and taxes and do not specifically monitor the start and stop times of employees' work on projects.
