The answer is: [B]: 3.
______________________________________________
Let us assume that the problem is meant to be written as:
_______________________________________________
  2a / (3b - c) ;

Explanation:
___________________
we are given the values for "a", "b", "c" ; and we are asked to solve the problem when the given values: 
      a = 6, b = 4; and c = 8 .
________________________
Note:
________________________
We have a "numerator" , " 2a " ; and a "denominator" , (3b - c).
_______________________
Let us start by finding the numerator: 
_________________________________
Numerator: 2a = 2*a = 2 * 6 = 12.
_______________________________________
Denominator: 3b - c  = (3*4) - 8 = 12 - 8 = 4
_______________________________________
To solve: Numerator ÷ Denominator = 12 ÷ 4 = 3.

The answer is: [B]: 3.
