Multiple Choice

Which of the following is NOT a phase identifier mentioned as used by some companies?

Phase identifiers are typically simple, easy-to-remember sequences used to mark stages in a process. You’ll often see patterns like ABC, XYZ, or 123 because they clearly show progression and are quick to reference in conversation and documentation. DEF, starting later in the alphabet, isn’t commonly cited as a standard phase labeling sequence in practice. Since ABC, XYZ, and 123 are the kinds of sequences you’ll encounter in real-world examples, DEF is the one that isn’t mentioned as a typical phase identifier.
