The correct option is Outgoing Mail.

Outgoing Mail is the Jira administration area that controls whether the application sends notification emails to users and watchers when issues are updated. If notifications stopped after a change in behavior this is the place to confirm that outgoing email is enabled and to send a test message or view the mail queue and delivery status.

Mail Handler is incorrect because mail handlers deal with incoming email and how Jira creates or updates issues from messages. That setting does not control whether Jira sends notification emails to watchers.

SMTP Mail Server is not the best choice because it normally refers to the low level SMTP server details rather than the switch that enables outbound notifications in the admin UI. In some older Jira versions server entries were managed separately so this option may appear as a legacy configuration on older exams.

Personal Settings is incorrect because Maya already checked her personal preference for watching issues and those settings apply per user. Personal settings will not stop all outgoing mail from the system when the global outgoing mail capability is turned off.

Global Mail Settings is incorrect because the modern admin workflow uses the Outgoing Mail page to enable and troubleshoot notifications. If a legacy named page appears on older documentation it is functionally replaced by the Outgoing Mail controls in current versions.
