Selected Answer: C
### Notes on other options: - **A** Inaccurate: The cost of each ToR switch may be lower, but the total number is what drives up the cost. - **B** Illogical: ToR switches are installed in the same rack as the servers and do not require a separate rack. - **D** Incorrect: ToR switches do not rely solely on optical interfaces; they often include copper interfaces as well.
