Consider the following information for four portfolios, the market, and the risk-free rate (RFR):

Portfolio	Return	Beta	SD
A1	0.15	1.25	0.182
A2	0.1	0.9	0.223
A3	0.12	1.1	0.138
A4	0.08	0.8	0.125
Market	0.11	1	0.2
RFR	0.03	0	0

Calculate the Sharpe Measure for each portfolio.

	a.	A1 = 0.54, A2 = 0.68, A3 = 0.65, A4 = 0.40
	b.	A1 = 0.66, A2 = 0.31, A3 = 0.65, A4 = 0.40
	c.	A1 = 0.66, A2 = 0.65, A3 = 0.31, A4 = 0.40
	d.	A1 = 0.40, A2 = 0.31, A3 = 0.65, A4 = 0.66
	e.	A1 = 0.31, A2 = 0.66, A3 = 0.65, A4 = 0.40
