**Question:**
What is the number of connected components for each of the following graphs?

---

**Graph (a):**

- **Description:** 
  - This graph consists of two distinct parts:
    1. A diamond-shaped subgraph with vertices labeled \( a, b, c, d \).
    2. A linear segment with vertices labeled \( f, g, h \).
    - Additionally, vertex \( e \) is isolated.
    
- **Answer:** 

  - The correct number of connected components is 3 (not 7 as shown in the incorrect answer).

---

**Graph (b):**

- **Description:** 
  - A star-shaped configuration with intersecting lines forming a hexagon.
  - Vertices are labeled \( u, v, w, x, y, z \) in a connected hexagon.

- **Answer:** 

  - The correct number of connected components is 1 (not 6 as shown in the incorrect answer).

---

**Graph (c):**

- **Description:** 
  - This graph includes:
    1. A central node \( i \) connected to nodes \( a, b, c, d, e, h, j \).
    2. A self-loop at node \( c \).
    3. A separate linear segment with vertices \( f, g \).

- **Answer:** 

  - The correct number of connected components is 2 (not 8 as shown in the incorrect answer).
  
---

**Note:** In graph theory, a connected component is a maximal set of vertices such that each pair of vertices is connected by a path. Understanding the number of connected components helps in analyzing the structure and connectivity of graphs.
