The personal pronoun that agrees with the underlined antecedent is:
The
Explanation:
The reason behind this answer is that "it" is the personal pronoun to refer to neuter gender objects like a guitar or a car. However, to refer to that object in a third-person scheme when we are going to include the specific name of the object we use "the" as a predecessor to refer to it in first place or introduction. Then if we are going to complement that sentence with another one we will use the personal pronoun it. Animals, transports and some countries use a female pronoun to be identified.
