The correct option is
C Edges= 12 , Vertices =6
A face is a single flat surface of the object. An edge is a line segment between faces and a vertex, is the corner point where two or more edges meet.
So, the given figure has
6 vertices (A,B,C,D,E,F) and
12 edges (AD, AE, AB, AF, CD, CF, CB, CE, DE, EB, BF, FD).
