In the sentence "the report arrived too late to be of any value to me," which word is a pronoun?

The word "me".

Explanation:

Pronoun is the class of words that replaces the noun. It is intended to indicate the person of the speech or to locate in time and space, without using his name.

Pronouns have several characteristics: they form various closed morphological systems (me, I, you, he / she, mine, yours, yours, etc.); most accept, like names, morphemes of gender and number; they act by allusion to something already mentioned or implicit in the message or in the linguistic or extralinguistic context, maintaining, even when isolated, a generic semantic basis capable of referring to another lexical realization, etc.

often a noun phrase is just a noun or a pronoun:

people like to have money.

i am tired.

it is getting late.

the answer is c. the wind
