Yes, C.

To determine which ratio forms a proportion, we need to check if the two ratios are equal.

Let's check each option:

A. 3/15 = 0.2 and 12/55 ≈ 0.2182... These ratios are not equal.

B. 8/24 = 0.3333... and 12/35 ≈ 0.3429... These ratios are not equal.

C. 5/18 ≈ 0.2777... and 25/90 ≈ 0.2777... These ratios are equal.

D. 4/11 ≈ 0.3636... and 16/25 = 0.64. These ratios are not equal.

Therefore, the ratio that forms a proportion is C. 5/18, 25/90.
