Study the following information carefully and answer the questions given below:
In a certain code language:
“Summer season is boring” is coded as “mn hn rd hi”
“Winter season are gone” is coded as “jk hn tr vb”
“People feel boring summer” is coded as “mn rd bx az”
“boring feel are gone” is coded as “rd jk vb az”

The code of “hn az” is stand for which of the following words?

The correct answer is season feel.

To find the code for "hn az", we can decipher the code language step-by-step by comparing the given statements:
1. “Summer season is boring” is coded as “mn hn rd hi”
2. “Winter season are gone” is coded as “jk hn tr vb”
3. “People feel boring summer” is coded as “mn rd bx az”
4. “boring feel are gone” is coded as “rd jk vb az”

Step 1: Find the code for "season"
Comparing Statement 1 and Statement 2, the only common word is "season" and the only common code is "hn".
Therefore, season is coded as hn.

Step 2: Find the code for "feel"
Comparing Statement 3 and Statement 4, the common words are "feel" and "boring", and the common codes are "rd" and "az".
To identify which is which, we compare Statement 1 and Statement 3, where the common words are "summer" and "boring", and the common codes are "mn" and "rd".
Since "boring" is present in Statements 1, 3, and 4, its code must be the common code among them, which is rd.
Since "boring" is coded as rd, the code for feel must be the remaining code from the "feel/boring" pair, which is az.

Conclusion:
Combining our findings, hn stands for "season" and az stands for "feel".
Thus, the code "hn az" stands for "season feel".
