Complete step-by-step answer:
To find out what, the faces of a pentagonal pyramid consists of
Firstly, we need to know the definition of the term “pentagonal pyramid”. From the name you can already guess it is something related to pentagon and also pyramid. So in geometry a pentagonal pyramid is a pyramid with a pentagon base upon which are erected fixed triangular faces that meet at a point.
So, from the diagram and definition, you can conclude that there is a base which is pentagonal shape that means a plane figure that has five straight sides. On every side a triangle is created upward. So, from five sides total five triangles are erected and meet at the point at top. So in total there are six faces of the pentagonal pyramid, one of the faces is a pentagon, which is in the base and the other five faces are a triangle hence the option A, one pentagon and five triangles is the correct option.

Note: You can see pentagonal pyramid shaped objects in various places like classroom or playing and learning stuff of kids etc. You should know the definition of pentagonal pyramid and how it looks before solving this question.
