Which AWS service or feature should the company use to determine the Regions that offer the lowest price?

Explanations:

Cost Explorer is used for analyzing spending patterns and visualizing AWS costs over time, but it does not provide real-time pricing comparisons between different AWS Regions.

AWS Budgets is primarily used to set and track budgets for AWS usage and costs. It does not help in comparing prices across AWS Regions.

AWS Trusted Advisor offers best practices and insights for optimizing AWS usage, but it does not focus on pricing comparisons between Regions.

AWS Pricing Calculator allows users to estimate costs for AWS services and provides the capability to compare prices across different Regions, making it the best choice for identifying the lowest-priced Regions.
