Answer:
The pronoun(s) is/are: she; it
Step-by-step explanation:
Process of elimination: it can't be diploma because that's a noun. She is a pronoun so we know it's either a. or d. It is also a pronoun so the answer is D. She; it.
A pronoun is a word that can function by itself as a noun phrase and that refers either to the participants in the discourse (e.g., I, you ) or to someone (or something) mentioned elsewhere in the discourse (a formal discussion of a topic in speech or writing) (e.g., she, it, this ).
So, the pronouns are she and it. Therefore, it's D.
