Given the following information about interest rates, which of the following solutions is correct? Note that the coupon bond pays coupon twice per year.

Par (Face Value)	Maturity, years	Coupon, % per annum	Price	Discount factor	Interest rate, r
100	0.5	0	97	0.9700	6.0918%
100	1	0	93.75	0.9375	6.4539%
100	1.5	6	98	d	r

	a.	Coupon = $3; d = {98 (3 * 0.9700 + 3 * 0.9375)} / 100 = 0.9228; r = -1/1.5 * ln(0.9228) = 5.3580%
	b.	Coupon = $3; d = {98 (3 * 0.9700 + 3 * 0.9375)} / 103 = 0.8959; r = -1/1.5 * ln(0.8959) = 7.3286%
	c.	Coupon = $6; d = {98 (6 * 0.9700 + 6 * 0.9375)} / 100 = 0.8655; r = -1/1.5 * ln(0.8655) = 9.6260%
	d.	Coupon = $6; d = {98 (6 * 0.9700 + 6 * 0.9375)} / 106 = 0.8166; r = -1/1.5 * ln(0.8166) = 13.5106%
