Sales reps at Cloud Kicks want to be notified when they have a high likelihood of winning an opportunity over $1,000,000. Which feature meets this requirement?

Big Deal Alerts is a standard Salesforce feature specifically designed to notify specified users (like sales reps or management) via email when an Opportunity meets predefined criteria, such as a high amount (e.g., over $1,000,000) and a high probability (e.g., Stage equals "Proposal/Price Quote" or "Negotiation/Review").

The Activity Timeline displays past and upcoming activities related to a record, but it does not provide proactive alerts based on opportunity criteria.

"Key Deals" is not a standard, configurable alerting feature in Salesforce; it might be a custom field or a generic term for important opportunities.

A Performance Chart is a reporting tool used for visualizing sales metrics and trends, not for sending automated notifications about specific opportunity events.
