C is the answer. Think of a triangle base with another triangle of the same shape above it with lines connect the three vertices of the bottom triangle to its corresponding vertices on the triangle up top.
7 years later and im using it ;
The solid figure with six vertices is the Triangular Prism (Option C), which consists of two triangular bases connected by three rectangular faces. This configuration creates a total of 6 vertices. Other options have different vertex counts, establishing the triangular prism as the correct answer.
