Bill Dauber correctly thinks of his customer relationships as a portfolio because:
| a. | 
 the uniform commercial code classifies them this way  | 
|
| b. | 
 he must be in the financial services business  | 
|
| c. | 
 they constitute sources of risk and return  | 
|
| d. | 
 all of the above  | 
|
| e. | 
 they are uniform in the type of risk they constitute  | 
c. they constitute sources of risk and return
It is being considered as a portfolio because just like a portfolio, it constitutes the sources of Investments held by an organization or individual which will possess both risk and return as well.
