    Answer: (4) 6 : 8 : 9
    Explanation:-
    A : B = 3 : 4  and B : C = 8 : 9

    Formula-
    A : B  = a ; b   B : C =  b : c 
    Then, A : B : C = a x b : b x b : b x c 

    Then, A : B  :  C = 3 x 8 :  4 x 8 : 4 x 9
    = 24 : 32 : 36
    Divide by 4,
    = 6 : 8 : 9

    Then, the value of A : B : C = 6 : 8 : 9.

    Hence, the answer is (4) 6 : 8 : 9.
