Assuming the underlined word is "leader," the correct answer is predicate nominative. Predicate nominative refers to a word that is in the nominative case and completes a copulative verb. In this sentence, the word "leader." Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help.
