From the given information, determine the code for each letter:
RAIN = 9432
- R = 9
- A = 4
- I = 3
- N = 2
WET = 865
- W = 8
- E = 6
- T = 5
Using the decoded values, encode INTERNET letter by letter:
I = 3
N = 2
T = 5
E = 6
R = 9
N = 2
E = 6
T = 5
Combining the codes in sequence:
INTERNET = 32569265
Therefore, the answer is Option 4: 32569265
