Question Analysis
This question tests the ability to determine similarity across different 3D figures by comparing ratios of corresponding linear dimensions.
The main focus is applying the similarity criteria consistently to prisms, cylinders, and pyramids.

Key Concept Explanation
For two 3D figures to be similar, all corresponding linear dimensions must be in the same ratio (scale factor).
This includes length, width, height for prisms; radius and height for cylinders; and base sides and height for pyramids.

Step-by-Step Solution
Option A:  
 . All ratios are equal, so prisms are similar.  
Option B:
