Final answer:
A backout is the reversion from a change that had negative consequences in software development or database management, aiming to return to a previous stable state. So the correct answer is C.
Step-by-step explanation:
The question asks which of the following options represents a reversion from a change that had negative consequences. A backout is a process in software development or database management where changes that have been made, and that have caused unintended or negative consequences, are reverted to a previous stable state. This differs from a backup, which is a saved copy of data that can be used to restore systems in case of data loss. The other options, ERDC and DIS, do not refer to the process of reverting changes due to negative consequences.
Option A, "Backup," involves creating a copy of data or system configurations for the purpose of recovery, but it doesn't specifically address the reversal of changes made.
Option B, "ERD" (Entity Relationship Diagram), is a visual representation of the relationships among data within a database and is unrelated to the concept of reverting changes.
Option D, "DIS," is not a recognized term in this context and doesn't relate to the reversion of changes.
In summary, the term "Backout" directly signifies the process of reverting from a change that had negative consequences, making it the most appropriate choice in this context.
