To calculate the average growth rate, we can use the formula: 
[(Ending Population / Beginning Population)^(1/Number of Years)] - 1

Plugging in the numbers, we get:
[(6,000,000,000 / 600,000,000)^(1/300)] - 1
= (10^(1/300)) - 1
= 0.0077 or 0.77%

Therefore, the average growth rate over that period was 0.77%, which corresponds to choice B.
