Explanation
In the given code language, each letter of a word is replaced by a unique digit, and the same letter is always replaced by the same digit.
Using this code, we can find the code for the word 'GREEN' as follows:
G → ? (not given)
R → 1
E → ? (not given)
E → ? (not given)
N → 7
We can see that we don't have the codes for the letters G and E. Therefore, we cannot determine the code for the word 'GREEN'.
Therefore, the answer is (D) Cannot be determined.
