The figure below shows the possible routes from city A to city M as well as the cost (in dollars) of a trip between each pair of cities (note that if no arc joins two cities it is not possible to travel non-stop between those two cities). A traveler wishes to find the lowest cost option to travel from city A to city M. A 20 B 11 21 D E 14 23 14 H 10 11 K 18 23 21 M

Question
**Description:**

The diagram illustrates a network of possible routes from city A to city M, along with the travel costs in dollars between connected cities. If two cities are not directly connected by a line (arc), there is no direct travel route between them.

The objective is for a traveler to find the least expensive path from city A to city M.

**Graph Explanation:**

- **Nodes (Cities):** A, B, C, D, E, F, G, H, I, J, K, L, M.
- **Arcs (Travel Routes with Costs):**
  - A to B: $20
  - A to C: $16
  - B to D: $11
  - B to E: $21
  - C to F: $14
  - D to G: $23
  - E to I: $15
  - F to I: $14
  - F to H: $8
  - G to J: $14
  - G to I: $9
  - H to K: $10
  - I to M: $23
  - J to L: $18
  - K to I: $11
  - L to M: $21

**Question:**

Which of the following paths would be infeasible?

The diagram implies that paths (routes) directly between cities that have no connecting arc are infeasible. Thus, a proposed path that jumps from a city to another without a direct or sequential connection is not possible.
