Final answer:
To find the most recent version of the file named Project.docx, Samir should check the Date Modified property, which indicates the latest time the document was edited.
Step-by-step explanation:
Samir should examine the Date Modified property to find the most recent version of Project.docx. This property shows the last date and time the file was changed. The Date Created might show when the file was originally made, but it won't indicate subsequent changes. The Date Accessed reveals the last time the file was opened, which doesn't necessarily mean it was modified then. Date Taken is primarily related to digital photographs and the date the picture was captured, hence it's irrelevant for text documents like a .docx file. Therefore, to locate the latest version of a document based on its modifications, Samir should sort or search his files by the Date Modified attribute.
