Step-by-step explanation:
Correct option is D
Euler's polyhedron formula, V−E+F=2
V = number of vertices = 6
E = number of edges = 12
F = number of faces = ?
6−12+F=2
F=6+2
F=8
Number of faces = 8
A octahederon has8 faces and 6 vertices with 12 edges.

answer:
(d) 8 faces
because if we try Euler formula
f + v - e =2
8 + 6 -12 =2
14 - 12 =2
we got the answer
