Option A: 3.1196% compounded semiannually.

where r = 3.1196% or 0.031196

n = 2

[tex] Effective Rate of return = (1 + 0.031196/2)^2 - 1 [/tex]

OPTION A : Effective Rate of return = 3.144%

OPTION B: 3.1172% Compounded Monthly

where r = 3.1172% or 0.031172

n = 12

[tex] Effective Rate of return = (1 + 0.031172/12)^12 - 1 [/tex]

OPTION B: Effective Rate of return = 3.162%

OPTION C: 3.1095% Compounded Daily

where r = 3.1095% or 0.031095

n = 365

OPTION C :Effective Rate of return = 3.158%

OPTION D: 3.1184% Compounded Quarterly

where r = 3.1184% or 0.031184

n = 4

[tex] Effective Rate of return = (1 + 0.031184/4)^4 - 1 [/tex]

OPTION D :Effective Rate of return = 3.155%

Therefore, OPTION B provides 3.162% the highest APY as compared to the other options.
