A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
A new FinOps practice needs one place in Azure to analyze spending, monitor it against budgets and find savings. Which of these fits that need?
Correct.

Why B
The source explicitly states Cost Management is a suite of FinOps tools that help organizations analyze, monitor, and optimize their Microsoft Cloud costs.
