Correct Answer
D) Hours, labor classifications, material invoices, and equipment usage are poorly documented

Why This Is the Correct Answer
T&M work depends on reliable documentation of hours, classifications, materials, equipment, and rates. Poor records make entitlement and pricing disputes more likely.
Why the Other Options Are Wrong
Option A: Daily records are signed and rates were agreed in advance, leaving time-and-material work unverified
Choice A (Daily records are signed and rates were agreed in advance) is rejected because it answers the Time-and-material work prompt with the wrong practical move.
Option B: The scope is authorized in writing
In procurement and contracting, The scope is authorized in writing is the wrong selection for Time-and-material work: it leaves out the controlling Time-and-material work result: Hours, labor classifications, material invoices, and equipment usage are poorly documented.
Option C: The work is tracked each day
The trap in C is The work is tracked each day. That selection is wrong because the choice would not get the project to Hours, labor classifications, material invoices, and equipment usage are poorly documented, which is the Time-and-material work result verified by the source; T&M work needs.
Memory Technique
Use time-and-material work as the label and Hours, labor classifications, material invoices, and equipment usage are poorly documented as the definition to recall under pressure.
