Among maintenance contract models, the Lowest-Risk option is the:

Comprehensive Contract

A comprehensive maintenance contract includes:

Preventive maintenance

Corrective maintenance

Replacement parts

Labor costs

Priority response times

Faster repair and recovery

Predictable costs

Strong service guarantees

Higher reliability and lower operational risk

Why other options are incorrect:

A -- Basic: Limited coverage; higher risk of delays.

B -- Time & Material: Highest financial and operational risk.

D -- Exclusive: Typically an enhanced premium model but not the primary ''lowest risk'' category in EPI's standard contract structure.

Thus, C is correct.
