Show the answer and explanation
CorrectNot quiteAnswer B
Correct answer: B
Explanation
B = 2, E = 5, D = 4, and the code numbers are 4, 25, 16, which are 2², 5² and 4².
So each letter is replaced by the square of its position.
HAD: , , , giving 64-1-16.
Worth noting
16-2-8 doubles the positions instead of squaring them; for B = 2 both give 4, so check E: , not 25. 64-2-16 wrongly squares 1 as 2.
