The answer is:  [A]:  " \frac{5}{21} " .
________________________________________
Given: 

2/ (7x) = 6/5; 

→  (6/5) * (7x) = 2 ; 

42x / 5 = 2 ; 

42x = 2*5 ; 

42x = 10 ; 

42x /42 = 10/42 ; 

x = 10/42 = (10÷2) / (42÷2) = 5/21 ; 

x = \frac{5}{21} ;

→  which is:  Answer choice:  [A]:  " \frac{5}{21} " .
