The correct option is D 1100
The initial population was 1000, number of births were 50, deaths 75, migrantion into the area was 200, migrants moved out of the area were 75. New population= 1000 + birth rate - death rate + migrants moved in - migrants moved out; Population = 1000+50-75+200-75 = 1100.
