The use case point method of estimating the cost of software considers?

The use case point method of estimating the cost of software encompasses a holistic approach that includes various factors to arrive at an accurate estimation of project effort and cost. This method incorporates several key components:

1. Unadjusted Actor Weight: This factor considers the different types of users or systems that interact with the software. Actors can be classified as primary or secondary, and their complexity influences the overall effort required during development.

2. Unadjusted Use Case Weight: This takes into account the various use cases or functionalities within the system. Each use case is assessed based on its complexity, with more complex use cases contributing more heavily to the overall cost estimation.

3. Technical Complexity Factor: This factor evaluates the technical challenges and risks associated with the project. It accounts for aspects such as performance constraints, integrations, and architecture considerations, which can significantly impact the development effort.

By integrating these three components, the use case point method provides a systematic way to estimate project costs based on functional requirements and their interactions. This comprehensive approach ensures that all aspects of the software's complexity and its interactions with users and other systems are considered, leading to more accurate and reliable estimates. Thus, the correct choice, being all of the above factors, reflects the
