Answer:
Option D.
Step-by-step explanation:
A triangular prism has 5 faces, 2 triangular faces and 3 rectangular faces.
If we calculate the edges of each face then we get
2 triangular faces = 6 edges
and 3 rectangular faces have edges = 3, other edges of the rectangular faces are common with the triangular faces.
Therefore, total number of faces = 6 and total number of edges = 9 will be in a triangular prism.
Option D. triangular prism is the answer.
