Answer:
The answer is: I) Banks have more diversified asset portfolios
Explanation:
Commercial banks receive deposits from clients and work with a variety of accounts; from personal or commercial loans, letters of credit, movement of funds, to a whole variety of different assets depending on what financial powers have been granted to them by the state or federal law by which they operate.
Instead Thrifts (saving and loans associations) usually specialize in real estate lending and Credit Unions offer their services only to their members.
