In a code, WATER is written as XBUFS. Following the same rule, FIRE is written as

  • A. GJSF
  • B. EHQD
  • C. GJSG
  • D. GKSF

Explanation

Each letter advances by one, so F becomes G, I becomes J, R becomes S and E becomes F. The example confirms the rule on all five of its letters. Consistency across the whole example is what distinguishes a genuine rule from a coincidence.
