Which type of message trails or is attached to a preceding message?

• A. Strangler
• B. Flash
• C. Propagation
• D. Code Dress

Answer: (A)

Flash messages are temporary notifications that follow a user action. After you perform something—like submitting a form—the system stores a short message and then shows it on the next page load. This makes the message “trail” the preceding action: you get immediate feedback on the subsequent page, and the message typically disappears after being shown once. This behavior is commonly implemented by keeping the message in a temporary store (like a session) and clearing it after display.

The other terms don’t describe this one-time, next-page notification. The strangler pattern is about gradually replacing parts of a system, not about user messages. Propagation refers to spreading information or signals, not attaching a single ephemeral notice to the next view. Code dress isn’t a standard concept for user feedback messages.
