Please refer . . . . . . . . the notes at the end for more information. A. to B. for C. in D. of

The correct answer is: to.

The word “to” is used to indicate a destination or goal. In this case, the speaker is asking the listener to refer to the notes at the end of the document for more information. The other options do not make sense in this context.

• For is used to indicate a purpose or reason. For example, “I went to the store for milk.”
• In is used to indicate a location or position. For example, “The book is in the library.”
• Of is used to indicate possession or association. For example, “The car is of the red color.”
