The answer is 'e', seems straight forward unless I am missing something:

P(1+r/100)^T = 1000(1+(5.6/100))^3=1000(1.056)^3

Well in this question you actually dont. Two answers give you a total of over 3000, and the other two less than 1001. If you are investing your money for 3 years at 5.6% and tripling the amount then there is something shady going on, likewise if you earn only $1 then it aint worth investing :)
