Count the faces here.
Choose the group that has fewer faces than in the picture above.
There are 4 faces at the start.
Group A has 6 faces.
Group B has 3 faces.
Group C has 4 faces.
3 is smaller than 4.
So, the answer is Group B because it has fewer than 4 faces.
Group A has more than 4 faces because 6 is bigger than 4.
Group C has an equal number of faces to the picture at the top.
Let's try some questions now.
