Please explain

1. Given answer choices are for a, b, c, and d

2. Answer choices are given for c, d, e, f

Assume that you are going to conduct BFS (= Breadth-First Search) for the following graph from the vertex c. Select the visiting sequence from the number 1 to fill the mark array as you learned in the lecture. When you traverse the graph, you should follow our convention (= alphabetical order of vertex characters). Assume that you are going to conduct DFS (= Depth-First Search) for the following graph from the vertex a. Fill the mark array for the vertices c,d,e, and f as you learned in the lecture. When you traverse the graph, you should follow our convention (= alphabetical order of vertex characters)
