Explanation:

Let’s take this step by step:

- The word is DISTINGUISH.

- Third letter: S

- Sixth letter: N

- Eighth letter: U

- Eleventh letter: H

- So, letters: S N U H

Now, the question:

- Can you make a meaningful word with these? Let’s see—

- SUNH? No.

- HUNS? Yes, "HUNS" is a word (like the group from history).

- SHUN? Yes! "SHUN" is also a real word.

Here’s the catch:

- Since you can make more than one word ("HUNS" and "SHUN"), the answer should be M.

Now, the options:

- 1: S

- 2: X

- 3: M

- 4: N

- 5: H

The right one is Option 3: M.
