A ? D

B 35 C

D 189 E

A.64 B.65 C.66 D.67

i think its A.64 cause

C comes before D and E comes after D so,

we can write it up side down in order like this

B 35 C

A ? D

D 189 E

so we can see if we write 64 then we can take 35's 3 and multiply it by 6 and we get 18 so now we have removed

35's 3 and 189's 18 and now we are left with 35's 5 and 189's 9 and 64's 4 so if we add up 35's 5 and 64's 4 to get 189's 9
