Final answer:
Option (C), The question is about managing Apex jobs in Salesforce. Before deploying changes to an Apex class, use the deployment pipeline to unschedule existing jobs, and after deployment, reschedule them to work with the updated Apex code.
Step-by-step explanation:
The question pertains to the management of Apex jobs in the context of Salesforce deployment. When you apply changes to an Apex class, you should leverage the deployment pipeline to unschedule the existing Apex jobs before the deployment takes place. Once the changes have been successfully deployed, you would use a second deployment step to reschedule the Apex jobs so that they can operate with the newly modified Apex code. Considering the context of the information provided in the question, the most accurate answer would be option C) Pipeline / unschedule / jobs / deployment.
