Answer:
C
Step-by-step explanation:
Calculate the distance using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = E(- 2, 2) and (x₂, y₂ ) = F(4, - 6)
EF = 
     = 
     = 
     =  = 10 → C
 = 10 → C

The calculations for 2, 4, 8 year can be derived as follows,
For simple interest:
                    S.I = 
P= principle
T= Time
R= Rate
 For 2 year; 
             S.I =  =  $224
=  $224
            Amount = $2224
For 4 year;
             S.I =  = $448
= $448
            Amount = $2448
For 8 year;
              S.I =  = $896
= $896
            Amount = $2896
