D Correct answer
Explanation

This asks which statement is NOT true. Options A, B, and C are all true: a dodecahedron has 12 faces, in spherical geometry parallel lines do meet, and a square is a special type of rhombus. Option D is FALSE because there are exactly 5 Platonic solids (tetrahedron, cube, octahedron, dodecahedron, icosahedron), not 6. Therefore D is the correct answer to 'which is not true'.
