Plza need help plz have merrys on me

C.

Step-by-step explanation:

If you were to divide 54/9 you would get 6 and then you would also divide 6/3 and get 2 which would not be equal to 6. Then for B you would divide 2/1 and get 2 and then you would divide 1/2 giving you .5 which also doesn't equal 2. For C. you would divide 3/4 giving you .75 and then you would divide 9/12 which would also give you .75, but just to be certain that is the correct answer you would divide 7/9 giving you .78 and you would also divide 8/9 which would give you .89 and since they do not equal each other the only possible answer would be C.
