Show the answer and explanation
CorrectNot quiteAnswer B
Correct answer: B
Explanation
Split BRIGHT into pairs: BR, IG, HT. The code RB, GI, TH swaps the two letters of each pair.
STREAM in pairs: ST, RE, AM. Swapping each gives TS, ER, MA.
The code is TSERMA.
Worth noting
MAERTS reverses the whole word, and EAMSTR swaps the two halves. Neither gives RBGITH from BRIGHT, so neither is the code.
