The correct option is B no
Given, number of edges (E)=4,
number of faces (F)=5
and number of vertices (V)=3
The Euler formula gives the relation between the number of faces(F), vertices(V) and edges(E) of any polyhedron, which is given by:
F+V−E=2
Let's find F+V−E:
F+V−E=5+3−4
=8−4
=4
≠2
Clearly, the given polyhedron does not satisfy the Euler's formula, therefore, a polyhedron with the given dimensions does not exist.
Option (b.) is the correct choice.
