Answer 1

A solid that could be cut by a plane parallel to its base to form a circular cross section would be a **right cone**. The reason for this is that slicing through a cone parallel to its base results in a circular cross section, whereas the other options (rectangular prism, right pentagonal prism, and right hexagonal prism) would yield cross sections that are either rectangles or other polygonal shapes.

Therefore, the answer is **right cone**.
