Answer:
(C) Cylinder
Explanation:
Out of cone, prism and pyramid and cylinder, the cylinder has two congruent parallel discs for bases as A cone and a pyramid do not have parallel base, and they have a base with a vertice.
Whereas A prism and a cylinder have parallel bases. But the bases of a prism are not disc-shape, but the cylinder has bases as disc shaped, therefore cylinder is the only one which has two congruent parallel discs for bases.
Hence, option (C) is correct.
