If IMAGE and FIELD are coded as FHBNJ and EMFJG respectively, then which one among the given options is the most appropriate code for BEACH?

The correct option is IDBFC.

To find the code for the word BEACH, let us analyze the coding pattern used for the words IMAGE and FIELD.
The pattern involves two steps:
1. Reverse the order of the letters of the given word.
2. Shift each of the reversed letters forward by one position (+1) in the alphabetical order.

Step 1: Analyze "IMAGE" → "FHBNJ"
First, reverse the letters of the word IMAGE:
E, G, A, M, I
Next, shift each letter forward by one position (+1):
E + 1 = F
G + 1 = H
A + 1 = B
M + 1 = N
I + 1 = J
This gives the code FHBNJ, which matches the given pattern.

Step 2: Verify with "FIELD" → "EMFJG"
First, reverse the letters of the word FIELD:
D, L, E, I, F
Next, shift each letter forward by one position (+1):
D + 1 = E
L + 1 = M
E + 1 = F
I + 1 = J
F + 1 = G
This gives the code EMFJG, verifying our pattern.

Step 3: Apply the pattern to "BEACH"
First, reverse the letters of the word BEACH:
H, C, A, E, B
Next, shift each letter forward by one position (+1):
H + 1 = I
C + 1 = D
A + 1 = B
E + 1 = F
B + 1 = C
Combining these letters, we get the final code IDBFC.
