Which of the following is a difficulty in valuing collateralized mortgage obligations (CMOs) using Monte Carlo simulation or any other methodology? The issuer has distributed: 
 
 
| 
 A)  | 
both the prepayment risk and interest rate risk equally into different tranches. |    |  
| 
 B)  | 
both the prepayment risk and interest rate risk unequally into different tranches. |    |  
| 
 C)  | 
the prepayment risk into different tranches. |    |    
 
  
Some of the tranches are more sensitive to prepayment risk and interest rate risk than the collateral, while others are much less sensitive.   |
