The image contains a directed graph with seven vertices labeled as `a`, `b`, `c`, `d`, `e`, `f`, and `g`. The directed edges between these vertices are as follows:- `a` directs to `f`.- `a` directs to `c`.- `c` directs to `g`.- `g` directs to `b`.- `d` directs to `f`.- `d` directs to `e`.- `e` directs to `b`.- `e` directs to `f`.Below the graph is the question: "Which vertex would come first in a topological ordering of the vertices of the above graph?" This is followed by a dropdown selection box where the user is expected to choose the correct vertex.
