To get the status of an enqueued job for a class that implements the Queueable interface, a developer can:
Option C: View the Apex Jobs page
Correct Answer.
The Apex Jobs page in Salesforce Setup lists all asynchronous Apex jobs, including queueable jobs.
Developers can view the status, start time, and completion time of the job.
The AsyncApexJob object contains information about the status of asynchronous Apex jobs.
Developers can write a SOQL query to retrieve details about the queueable job using the job ID returned when the job was enqueued.
Example:
AsyncApexJob job = [SELECT Id, Status, NumberOfErrors FROM AsyncApexJob WHERE Id = :jobId]; The Apex Flex Queue is used for holding batch jobs that are waiting to be processed.
Queueable jobs are not placed in the Apex Flex Queue.
Option B: View the Apex Status page
Incorrect.
There is no specific "Apex Status" page.
This may refer to the Apex Jobs page.
Conclusion:
The two ways to get the status of an enqueued queueable job are C (Apex Jobs page) and D (Query the AsyncApexJob object).

Option D: Query the AsyncApexJob object
