Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
System.Queueable
Why this is correct
Correct. Queueable Apex allows a job to chain another job by invoking System.enqueueJob inside its execute method.
- ✗
Database.AllowsCallouts
Why it's wrong here
Incorrect. Database.AllowsCallouts is an interface marker used to permit HTTP callouts, not job chaining.
- ✗
System.Schedulable
Why it's wrong here
Incorrect. Schedulable runs jobs on a time-based schedule, not sequentially based on completion.
- ✗
Database.Batchable
Why it's wrong here
Incorrect. While Batchable has a finish method, it is designed for batch data processing rather than general sequential job chaining.
