The cloud characteristic that refers to resource utilization that can be optimized by leveraging charge-per-use capabilities is measured service. This is because measured service is a characteristic of cloud computing that involves monitoring, controlling, and reporting on the usage and consumption of cloud resources by cloud providers and consumers. Measured service helps to optimize resource utilization by leveraging charge-per-use capabilities, which means that cloud consumers only pay for the amount of resources that they actually use or consume, rather than paying for fixed or predetermined amounts of resources. The other options are not cloud characteristics that refer to resource utilization that can be optimized by leveraging charge-per-use capabilities, but rather different characteristics of cloud computing that describe other aspects or benefits of cloud services, such as on demand self-service (A), elasticity (B), or resource pooling (D).
