What is the correct knock pattern?

• A. Knock, Pause, Pause, Knock
• B. Knock, Pause, Pause, Pause
• C. Knock Knock, Pause, Knock, Pause, Knock Knock, Pause, Knock
• D. Knock, Pause, Knock, Pause, Knock

Answer: (C)

Think of this as a simple rhythm code where groups of knocks form units of a message and pauses separate those units. The pattern starts with two knocks in a row, which signals a first unit with extra emphasis. A short pause follows, then a single knock marks the next unit. After another short pause comes a double-knock unit again, then a final single knock. The alternating double-knock and single-knock grouping, separated by consistent pauses, creates a clear, interpretable sequence that matches the intended encoding. If the grouping changes—for example, turning the initial double into two separate single knocks, or inserting extra or fewer pauses—the rhythm no longer maps to the expected message, making the pattern less recognizable or correct.
