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.
