Answer 2

We need to fill the blank in the sentence and the correct answer will be if we will it with a preposition 'for'                    

• The sentence then becomes 'I exchanged my pen for a book '

• The word for used here is a preposition namely 'for'
• A preposition is a word that precedes a noun or pronoun and expresses a relationship with another word in the sentence
• Example after, in to
• In this sentence, the word 'for' has been used as a preposition
