I have come to understand that option iii is the best option. But please plug that into the final part of the question(Finding future/annual worth in 15 years) so please help me with that!

Problem 2 (35\%) Global Investment Corporation is exploring multiple investment opportunities to invest about $20M. Four investment opportunities are being carefully evaluated. If the company is interested in maximizing the return on investment, which one offers the best opportunity? i. 12% per year compounded quarterly. ii. 11.85% per year compounded daily. iii. 11.95% per year compounded monthly. iv. 11.82% per year compounded continuously. Show your calculation for each option and based upon your calculation select the best option from i to iv. Determine the future and annual worth of the investment with the best interest rate in 15 years from now
