Answer:
HOFO = (0, 0, +1, -1)
Explanation:
The formal charge (FC) can be calculated using the following equation:

<u>Where:</u>
V: are the valence electrons 
N: are the nonbonding electrons
B: are the bonding electrons
The arrange of the atoms in the oxyacid is:
H - O₁ - F - O₂ 
Hence, the formal charge (FC) on each of the atoms is:
H: FC = 1 - 0 - 1/2*(2) = 0             
O₁: FC = 6 - 4 - 1/2*(4) = 0        
F: FC = 7 - 4 - 1/2*(4) = +1 
O₂: FC =  6 - 6 - 1/2*(2) = -1 
We can see that the negative charge is in the oxygen instead of the most electronegative element, which is the F. This oxyacid is atypical.  
I hope it helps you!
 
        
             
        
        
        
B. slows down is your answer, obviously as it approaches carrying capacity, there would be less available space to find in the place of inhabitance, so less and less population units would be able to find the place of inhabitance suitable for living, or can't find enough space to live in.
