Which KPI represents the percentage of time that the infrastructure, system, or solution is operational under normal circumstances?

Explanation:
Availability measures the proportion of time a system or service is usable and performing as needed by users. It captures the idea of being able to access and rely on the infrastructure under normal operating conditions, not just that the hardware is powered on. In practice, you express availability as a percentage of the time the service is available, often accounting for planned maintenance and outages. This is why it’s the best fit for “the percentage of time the infrastructure is operational under normal circumstances.” Uptime is related but simply tracks the actual time the system is running, which doesn’t always reflect whether it’s really usable. Utilization looks at how much of a resource’s capacity is being used, and Performance Efficiency focuses on how effectively the system uses resources to meet requirements.
