Which underlined pronoun has a stated antecedent?

(it) is a book about planets.

(we) closely studied her book.

(he) presented us with his report.

(she) reads books in the library.

The underlined pronoun that has a stated antecedent is the pronoun "It" of the phrase " (It) is a book about planets. "

In this sentence, the pronoun "It" behaves as a relative pronoun, which is that which refers to a term previously mentioned which we call antecedent. The relative pronoun is given this name because it relates the antecedent to the following terms. In other words, "It," this is referring to a term that was quoted earlier and is an antecedent of "It".

the answer is subjective. i personally agree with the first answer for this question.

if one isn't strictly talking about objects then the correct answer would be 'my eyes' since according to this riddle i am asleep and in order to answer/open the door i need to open my eyes first of all.

however, if one is specifically looking for an object, then the first thing i would open would be the door

hope this !

i think it is b. hope this !
