Answer:B. Pyramids have triangular faces and a polygonal base.

Explanation:

A pyramid is a three-dimensional shape that has a polygonal base and triangular faces that meet at a single point called the apex. Here's how to identify which of the given descriptions best suits a pyramid:

A. Pyramids have polygonal faces and a triangular base.

This description is incorrect because pyramids have a polygonal base, not a triangular base.

B. Pyramids have triangular faces and a polygonal base.

This description is correct because it correctly identifies that pyramids have triangular faces and a polygonal (meaning multi-sided) base.

C. Pyramids have triangular faces and a circular base.

This description is incorrect because pyramids have a polygonal base, not a circular base.

D. Pyramids have polygonal faces and a polygonal base.

This description is partly correct because pyramids do have a polygonal base, but their faces are always triangular.

E. Pyramids have curved faces and a polygonal base.

This description is incorrect because pyramids have flat, triangular faces, not curved faces.

So, in summary, option B, "Pyramids have triangular faces and a polygonal base," is the description that best suits a pyramid.
