Answer:
By a process of elimination, the answer is:
B. provide liquid assets to lenders and long-term financing to borrowers.
Step-by-step explanation:
A. have customer deposits as its primary asset and loans to borrowers as their primary liability. ⇒ WRONG, IT IS THE OTHER WAY AROUND
C. are types of mutual funds. ⇒ WRONG, MUTUAL FUNDS ARE DIFFERENT THAN BANKS
D. have customer deposits as its primary asset and that provide liquid assets to lenders. ⇒ WRONG, DEPOSITS ARE LIABILITIES
E. increase transaction costs to both borrowers and depositors. ⇒ WRONG, BANKS DECREASE TANSACTION COSTS
Personally, I believe that a better description would be that banks have customer deposits as its primary liabilities and loans to borrowers as their primary assets.
