The correct response is:
Figure 1, Figure 2, and Figure 3; all figures are rectangles.
While it is true that Figure 1 and Figure 3 are rectangular and one is larger than the other, the question asks for similarity, which in this case refers to the categorization of the figures as rectangles. All three figures are indeed rectangles, which satisfies the requirement for similarity in the context provided. The other options do not correctly identify the relationship based on geometric similarity.
