Answer:
To
Step-by-step explanation:
- 'To' is the correct preposition to fill in the blank space.
- This is because to is used to describe the position of the class in a way that it does not directly describe the location.
- A preposition is a word used to show the relationship of the noun and the pronoun in a sentence.
- Two is used for numbering or to show the actually number or position
- Hence the sentence should read, we are going to class.
