I need help asap for this question

Answer:
Step-by-step explanation:
Well since AB/DE = 3/4 and AB/DE = BC/EF, then BC/EF must also be 3/4.
We now only need to find a fraction that simplifies to 3/4.
8/12 = 2/3 [tex]\neq[/tex] 3/4
12/16 = 3/4 ✅
4/6 = 2/3 [tex]\neq[/tex] 3/4
6/9 = 2/3 [tex]\neq[/tex] 3/4
This means that the correct answer is B. 12 and 16.
