To calculate the projected population for 2005, we can use the formula: 
Projected Population = Current Population x (1 + growth rate)^number of years
Substituting the given values, we get:
Projected Population = 5,594,000 x (1 + 0.016)^4
Projected Population = 5,594,000 x 1.067^4
Projected Population ≈ 5,960,700 (rounded to nearest hundred) 
Therefore, the best choice is C, which is closest to the calculated value.
