Answer:
A. 1100
Step-by-step explanation:
∵ The population which is increasing with the geometric rate of b is,

Where,
a = initial population,
Here, a = 10,
If the population is growing by the growth factor of 1.6,
i.e. b = 1.6,
Then the population after x years,

If x = 10,
Hence, the population after 10 years would be,

Option 'A' is correct
