Correct Answer: COURT

Solution : Given:
ENCOURAGE

Now, let's compare all the option words with the word ENCOURAGE –
First option: COURAGE; All the letters of COURAGE are present in the word ENCOURAGE.
Second option: COURT; T is not present in the word ENCOURAGE. Therefore, all the letters of COURT are not present in the word ENCOURAGE​​​​​.
Third option: RACE; All the letters of RACE are present in the word ENCOURAGE.
Fourth option: ENCORE; All the letters of ENCORE are present in the word ENCOURAGE.

So, COURT cannot be formed with the letters of the word ENCOURAGE. Hence, the second option is correct.
