T is a graph with n vertices. T is connected and has exactly n-1 edges, then :
Correct Answer: D
Question 1 Explanation:
This is little bit tricky question.
Step-1:
n= number of vertices
n-1 = number of edges
Example: n=5 vertices and n-1=4 edges
Step-2: The above graph T won’t have cycle then we are calling as tree. Here, every pairs of vertices in T is connected by exactly one path.
Note: The above properties is nothing but minimum spanning tree properties.
