We can solve it using exponential growth rate formula as below.
We have the exponential growth rate formula as
Final amount A=(principal value P)×e(rate of interes)(tome)
so from the given data we can extract the rate of interest of country A=0.001
country B=0.011
country C=0.028
country D=-0.004
Here we can see the highest growth rate is 0.028, so its the 1st answer
again the percentage growth rate for this country would be 0.028100=2.8% per year
