Answer:
B) George Washington was the first president of the United States
Explanation:
A predicate nominative is a noun or pronoun that follows a verb or linking verb and explains the subject.
The verbs in A, B, and C are is, seems, and is, respectively. However, the words following the verbs are adjectives. Beautiful, fun, and delicious are not nouns. This leaves B to be the correct answer, since, the first president, is a pronoun.
