Correct Option: C

AI Explanation

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) These are reusable job elements - This option is incorrect. Shared containers are not necessarily job elements. They can be used to share common resources or configurations across multiple jobs or projects.

Option B) They can only be used within a project - This option is incorrect. Shared containers can be used across multiple projects, not limited to a single project.

Option C) When shared containers are modified, modifications are reflected in all the jobs that use them - This option is correct. Shared containers allow for centralizing configurations or resources that are common to multiple jobs. When a shared container is modified, these modifications are reflected in all the jobs that use the shared container, ensuring consistency across jobs.

Option D) None of the above - This option is incorrect since option C is valid about shared containers.

The correct answer is C. This option is correct because shared containers allow for modifications to be reflected in all the jobs that use them.
