If SISTER is coded as RJRUDS, how will you code BROTHER?

Key pattern: letters are shifted alternately by −1 and +1, starting with −1 for the first letter.

• Example check with SISTER → RJRUDS confirms the pattern: S→R (−1), I→J (+1), S→R (−1), T→U (+1), E→D (−1), R→S (+1).

Apply the same pattern to BROTHER:

• B → A (−1)

• R → S (+1)

• O → N (−1)

• T → U (+1)

• H → G (−1)

• E → F (+1)

• R → Q (−1)

Final coded word: ASNUGFQ

Note: None of the provided options match this correct coded form; the option that is closest has the correct first six letters but the final letter is S instead of the required Q.
