Suggested answer: A

Explanation:

Reconciliation of total amounts by project is the best control to ensure that data is accurately entered into the job-costing system from spreadsheets. Reconciliation is a process of comparing two sets of data to identify any differences or discrepancies between them. By reconciling the total amounts by project from spreadsheets with those from the job-costing system, any errors or omissions in data entry can be detected and corrected. Validity checks are controls that verify that data conforms to predefined formats or ranges. They can prevent entry of character data into numeric fields, but they cannot ensure that the numeric data is correct or complete. Reasonableness checks are controls that verify that data is within expected or acceptable limits. They can detect outliers or anomalies in data, but they cannot ensure that the data matches the source. Display back of project detail after entry is a control that allows the user to review and confirm the data entered into the system. It can help reduce human errors, but it cannot guarantee that the data is accurate or consistent with the source.Reference:Information Systems Operations and Business Resilience,CISA Review Manual (Digital Version)
