Correct Answer: PRESIDENT

Solution : Given:
JURISPRUDENCE

Now, let's compare all the option words with the word JURISPRUDENCE –
First option: PRINCE; All the letters of PRINCE are present in the word JURISPRUDENCE.
Second option: PRUNE; All the letters of PRUNE are present in the word JURISPRUDENCE.
Third option: PRESIDENT; T is not present in the word JURISPRUDENCE. Therefore, all the letters of PRESIDENT are not present in the word JURISPRUDENCE .
Fourth option: PREJUDICE; All the letters of PREJUDICE are present in the word JURISPRUDENCE.

So, from the above, only PRESIDENT cannot be formed using the letters of the word JURISPRUDENCE. Hence, the third option is correct.
