Which option shows the proper Remove Strip message for AAL233?

• A. RS AAL233 (enter)
• B. SR AAL233 (enter)
• C. RS AAL233 2330 (enter)
• D. SR AAL233 remove strip (enter)

Answer: (A)

The message format being tested is the Remove Strip command using the standard shorthand. In this system, you issue Remove Strip with the flight identifier in the shortest, official form, then submit by pressing enter. That means the correct entry is the Remove Strip code followed directly by the flight number, and then the submit action. It is concise and uses the established abbreviation RS with the airline’s flight number, here AAL233, and then (enter) to finalize.

Using a different prefix isn’t correct for this command, so the version that uses SR instead of RS isn’t the proper Remove Strip message. Adding extra digits like 2330 introduces an unnecessary element that isn’t part of the Remove Strip command. Writing out the phrase remove strip instead of using the shorthand RS also isn’t the standard format for this action. The concise RS AAL233 (enter) is the correct, properly formatted Remove Strip message.
