Consider a T-bill with a rate of return of 5% and the following risky securities:

Security A: E(r) = 0.15; Variance = 0.04 Security B: E(r) = 0.10; Variance = 0.0225 Security C: E(r) = 0.12; Variance = 0.01 Security D: E(r) = 0.13; Variance = 0.0625

B. 0.087; 0.12

C. 0.114; 0.12

D. 0.795; 0.14

E. 0.295; 0.12
