Correct Answer

✅ Option d — EQHDMC

All Options:

  • AQEDHCM
  • BCMDHQE
  • CEQIFNE
  • DEQHDMC

Detailed Solution & Explanation

Let's analyze the shift pattern in coding TAP→SZO\displaystyle TAP \rightarrow SZO by looking at alphabetical positions:
T (20)→−1S (19)\displaystyle \text{T (20)} \xrightarrow{-1} \text{S (19)}
A (1)→−1Z (26)\displaystyle \text{A (1)} \xrightarrow{-1} \text{Z (26)} (circular backward shift)
P (16)→−1O (15)\displaystyle \text{P (16)} \xrightarrow{-1} \text{O (15)}

The pattern is a constant backward shift of −1\displaystyle -1 for each letter.

Now, let's apply this same shift of −1\displaystyle -1 to the letters of the word FRIEND\displaystyle FRIEND:
1. F (6)→−1E (5)\displaystyle \text{F (6)} \xrightarrow{-1} \text{E (5)}
2. R (18)→−1Q (17)\displaystyle \text{R (18)} \xrightarrow{-1} \text{Q (17)}
3. I (9)→−1H (8)\displaystyle \text{I (9)} \xrightarrow{-1} \text{H (8)}
4. E (5)→−1D (4)\displaystyle \text{E (5)} \xrightarrow{-1} \text{D (4)}
5. N (14)→−1M (13)\displaystyle \text{N (14)} \xrightarrow{-1} \text{M (13)}
6. D (4)→−1C (3)\displaystyle \text{D (4)} \xrightarrow{-1} \text{C (3)}

Combining these results, the code for FRIEND\displaystyle FRIEND is EQHDMC\displaystyle EQHDMC.

Hence, **Option D** is the correct answer.
