Answer: The correct answer is "B. may be less than the variance of the least risky stock in the portfolio.".
Explanation: If a stock portfolio is well diversified, then the portfolio variance may be less than the variance of the least risky stock in the portfolio.
This occurs because diversifying the risk results in a lower risk in the total portfolio.

Answer:
See below.
Explanation:
For a)
The money multiplier or the credit multiplier can be calculated as follows,
Money multiplier = 1 / reserve ratio
Multiplier = 1 / 0.12 = 8.33 times
For b)
For a negative $80 million change by the Fed there will be a total change in the economy of 80 * 8.33 = $666.4 million.
A -80 million change will contract money supply by $666.4 million in the economy.
For c)
This can be calculated by dividing the target by the money multiplier.
So to achieve a change of $500m the Fed will expand the money supply by
= 500 / 8.33 = $60.02m.
Hope that helps.
