hi can you help me with this question, a-b as well with explanations, thanks!

Which do you prefer: a bank account that pays 5.3% per year (EAR) for three years or a. An account that pays 2.4% every six months for three years? b. An account that pays 7.2% every 18 months for three years? c. An account that pays 0.39% per month for three years? (Note: Compare your current bank EAR with each of the three altemative accounts. Be careful not to round any intermediate steps less than six decimal places.) If you deposit $1 into a bank account that pays 5.3% per year for three years: The amount you will receive after three years is $ (Round to five decimal places.)
