Answer:
Predicate noun is the correct answer.
Explanation:
Predicate nouns are defined as the ones that have a dual function in a sentence: a completer or a modifier, also known as predicate adjective. The first category is a single noun or a noun phrase that renames the subject; it is accompanied with a form of to be or other verbs such as feel, become, seem, remain, stay, among many others. The second category modifies the noun and gives more information about it.
In the question, the predicate noun works as a completer, since it mentions the position Lauren occupies as vice president, so it renames the subject.
