The correct answer is
NHTRO

Analyzing the NORTH to HTRON Code

The question asks us to find the code for 'ORTHN' based on the example where 'NORTH' is coded as 'HTRON'. We need to identify the coding pattern.

Let's map the positions of the letters:

  • Original Word: N O R T H
  • Position: 1 2 3 4 5
  • Coded Word: H T R O N

Comparing the positions:

  • 'H' (Position 5) moves to Position 1.
  • 'T' (Position 4) moves to Position 2.
  • 'R' (Position 3) stays at Position 3.
  • 'O' (Position 2) moves to Position 4.
  • 'N' (Position 1) moves to Position 5.

The pattern is a simple reversal of the letters in the word.

Applying Code to ORTHN

Now, we apply this reversal pattern to the word ORTHN:

  • Word to Code: O R T H N
  • Position: 1 2 3 4 5

Reversing the order of the letters (5 4 3 2 1):

  • Position 5 ('N') becomes the 1st letter.
  • Position 4 ('H') becomes the 2nd letter.
  • Position 3 ('T') becomes the 3rd letter.
  • Position 2 ('R') becomes the 4th letter.
  • Position 1 ('O') becomes the 5th letter.

The resulting coded word is NHTRO.

This matches Option 2.
