Explanation:

- Let's break down the pattern of the code language:

- Each word seems to have a combination of a number, a letter, and a symbol.

- The number in the code is the count of letters in the word.

- The letter in the code is likely derived from the position of the first letter of the word in the alphabet.

- The symbol might not follow a direct discernible pattern, as we have single sentence data.

- Decoding the given sentence:

- ‘india’ is coded as ‘5D%’: "India" has 5 letters; 'I' is the 4th letter, but here it seems some manipulation results in 'D'.

- ‘have’ is coded as ‘4V@’: "Have" has 4 letters; 'H' is the 8th letter, possibly remains 'V' due to manipulation.

- ‘many’ is coded as ‘4N#’: "Many" has 4 letters; 'M' is 13th in alphabet, turned 'N' (as 13-1=12, 12th letter is ‘N’).

- ‘temples’ is coded as '7M&': "Temples" has 7 letters; 'T' is the 20th letter but we have 'M'.

- Analyzing options to find the code for ‘marriage’:

- “Marriage” has 8 letters.

- Following the pattern, the theoretical transformation for 'M' seems to involve altering to 'R'.

- So, the correct code is `8R#`.

- Option 4: 8R# is the correct answer.
