Per-option explanation
ACorrect

AWS Budgets

Correct. AWS Budgets lets you set a budget for cost or usage and automatically sends an alert when you approach or exceed it. You can catch unexpected cost increases early and respond.

BIncorrect

AWS Cost Explorer

Cost Explorer is a tool to visualize and analyze past costs.

Setting a budget and alerting on overrun is the role of AWS Budgets, so it is incorrect.

CIncorrect

Amazon S3

S3 is object storage.

It is not a cost-management tool that alerts on budget overrun, so it is incorrect.

DIncorrect

AWS CloudTrail

CloudTrail is an audit service that records the history of API operations.

It is not a tool that alerts on budget overrun, so it is incorrect.

Key Takeaway

'Set a budget' and 'overrun alert' point to AWS Budgets. Visualizing and analyzing past cost is Cost Explorer. Distinguish 'budget management' from 'analysis'.
