Correct option is D
Explanation:
Let’s analyze the coding pattern used for 'SUMMER' and 'WINTER':
1. SUMMER → S21M13E18:
The first letter 'S' is kept as is.
The second letter 'U' corresponds to 21, which is the position of 'U' in the alphabet (U is the 21st letter).
The third letter 'M' corresponds to 13, which is the position of 'M' in the alphabet (M is the 13th letter).
The fourth letter 'M' corresponds again to 13.
The fifth letter 'E' corresponds to 18.
The sixth letter 'R' corresponds to 18.
2. WINTER → W9N20E18:
The first letter 'W' is kept as is.
The second letter 'I' corresponds to 9.
The third letter 'N' corresponds to 20.
The next letters follow a similar transformation.
Now, applying the same pattern to 'AUTUMN':
The first letter 'A' corresponds to 1.
The second letter 'U' corresponds to 21.
The third letter 'T' corresponds to 20.
The fourth letter 'M' corresponds to 13.
The fifth letter 'N' corresponds to 13.
Thus, 'AUTUMN' will be coded as 'A21U20N13'.
