(. i screenshot the question and choices d: )

Figure 1)
lenght₁=14
width₁=3
heigth₁=4

Figure 2)
lenght₂=112
width₂=24
height₂=32

If these figure are similar, then:
length₁/lenght₂=width₁/width₂=height₁/height₂=ratio of the smaller figure to the larger figure

Therefore:
14/112=3/24=4/32=1/8

yes; 1/8
