**Question:**  
Which of the following graphs are bipartite?

**Graph A:**  
- This graph consists of two groups of vertices connected by edges: Group 1 includes vertices {S, T, U, V, W, H, X} and Group 2 includes vertices {R, Q}.

**Graph B:**  
- This graph is a complete graph with vertices {A, B, C, D, E, F, G}, where each vertex is connected to every other vertex.

**Graph C:**  
- This graph has vertices {S, T, U, V, W, H, X, R, Q} with multiple edges connecting them, forming various paths, but crossing edges suggest complexity in bipartite determination.

**Graph D:**  
- This graph consists of two sets of vertices: Group 1 includes {P, O, N} and Group 2 includes {Q, R, S, T}, connected by edges between these groups. There are no edges connecting vertices within the same group.

**Check Boxes:**
- □ A
- □ B
- □ C
- □ D

**Explanation:**  
A bipartite graph is one in which the vertex set can be divided into two disjoint sets such that no two graph vertices within the same set are adjacent.

**Consider the following graph:**

The provided graph is a pentagon-shaped complete graph with five vertices labeled as 'l', 'k', 'm', 'n', and 'o'. Each vertex is connected to every other vertex by edges, forming a complete graph, specifically denoted as \( K_5 \).

---

**Question:**

Which of the following graphs are subgraphs of the graph above?

- A. \( P_2 \)
- B. \( P_3 \)
- C. \( K_5 \)
- D. \( K_{1,4} \)
- E. \( C_4 \)
- F. \( K_{3,2} \)
- G. \( K_6 \)

---

**Graph Explanation:**

The diagram shows all possible connections (edges) between the vertices, indicating it is a fully connected graph, \( K_5 \), where each of the 5 vertices is connected to every other vertex. Subgraphs of this graph include any smaller configurations of nodes and edges within this structure.
