You are considering two investments. Investment A yields 10% compounded quarterly. Investment B yields i% compounded semiannually. Both investments have equal annual yields. Find the right financial model to find the value of i.

a {1 + (0.1/4)} = { 1+ (i/2)}

b (1 + 0.1)^4 = ( 1+ i )^2

c {1 + 0.1}^4 = { 1+ (i/2)}^2

d {1 + (0.1/4)}^4 = { 1+ (i/2)}^2
