The space figure that features two parallel, congruent circular bases is the cylinder. A cylinder is defined by its circular bases located at each end, which are identical in size and shape, and it connects these bases with a curved surface. This characteristic of having two congruent and parallel circular bases distinguishes it clearly from the other options. In contrast, a cone has a circular base but only one base and tapers to a point, while a sphere has no bases at all and is a perfectly round three-dimensional shape. A pyramid, on the other hand, has a polygonal base and triangular faces that converge at a point, rather than having two circular bases. Thus, the correct figure with the specified properties is indeed the cylinder.
