Hint: Face can be defined as the flat surface. In simple words, the face is the single flat surface. Coin can be defined as the piece of currency that is created out of metal and it is two sided with two flat surfaces.
Complete step-by-step answer: By observing both the sides of the coin, we can identify that the coin has two flat surfaces and therefore it has two faces. Its two faces are called as : Head and Tail From the given multiple choices, option B is the correct answer. So, the correct answer is “Option B”.
Note: Do not get confused with the terms such as edges, faces and corners. An edge can be defined as the line segment between the face, where the face is the single flat surface and the vertex is defined as the corner. Do not get confused that the coin has two faces but has three edges.
