To answer this question, we need to understand the terms related to software development and deployment.
Option A) Release of CR - This option is incorrect because a CR (Change Request) is a formal request to make a modification or fix in an application. It does not refer to the interim release of the application.
Option B) Maintenance of application - This option is incorrect because while the bug fix is a part of application maintenance, it does not specifically refer to the interim release of the modified code.
Option C) Release of patch - This option is correct because a patch is a small piece of code that is used to fix a specific issue or bug in an application. When the modified code is ready for deployment to fix the bug, it is released as a patch to address the issue.
Option D) Interim release of CR - This option is incorrect because the interim release refers to the temporary release of the modified code before the final release. CR (Change Request) is not specifically mentioned in this context.
The correct answer is C) release of patch. This option is correct because when a bug is found and a CR is raised, the modified code is released as a patch to fix the issue in the application.
