Edge A-B is chosen first because Prim's algorithm is a greedy algorithm that selects the smallest edge connecting the current visited set to an unvisited node. From the starting node A, edge A-B has the minimum weight among all edges incident to A leading to unvisited nodes.
Conditions: Node A is the starting visited node.; The algorithm follows the greedy rule of picking the minimum-weight crossing edge.

To start Prim's algorithm, create an empty list called 'visited' to track touched nodes, then pick an arbitrary starting node and add it to the visited list.
Conditions: The graph is weighted and connected.; You have a mechanism to track visited vertices (e.g., a list or set).
