What enables Apex triggers to execute without manual invocation?

1. Scheduled Jobs

2. Batch Apex

3. Autolaunched Flows

4. Database Changes.

The correct answer is: Database Changes.

Apex triggers are special pieces of code in Salesforce that automatically execute in response to specific events involving database records, such as inserts, updates, and deletes. The execution of these triggers is directly tied to changes in the database, meaning that anytime a record is modified in a way that meets the trigger's criteria, the associated trigger will automatically run. The option reflecting this mechanism is related to database changes. Specifically, when a record is created, updated, deleted, or undeleted, the corresponding trigger is fired without any manual intervention required. This real-time functionality allows developers to enforce certain business logic, perform validations, or initiate additional processing automatically. In contrast, the other options listed do not inherently provide the same automatic execution functionality based on database changes. Scheduled jobs, for instance, are designed to run at specified times, rather than in response to immediate data modifications. Batch Apex, while capable of processing large volumes of data, necessitates manual invocation or scheduling for its execution. Autolaunched flows can be triggered automatically but are typically initiated by specific actions or events set up within the Salesforce environment, not directly linked to database changes. Thus, the primary feature of Apex triggers, which distinguishes them from the other options, is their execution model that relies on changes
