I had only my class notes for which I had to prepare for my examination.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. with which I had to.
It is because we will remove 'for' and use 'with' instead of that. We are showing what the subject has used to prepare for his/her exams.
While doing that, the relation will be shown by using "WITH" because it connects the two incidents- the subject and the class notes.
