Add caption

How many nodes are there in flowgraph F?

1. 1. 9
2. 2. 10
3. 3. 11
4. 4. 12

Answer : 1. 9

Explanation Question 141

Above graph contains 9 nodes and 11 edges.
The nodes are nothing but vertices.
Here, In above given diagram the number of rounds are the nodes
The nodes are 1, (2,3), (4,5), 6, 7, 8, 9, 10, 11.
Count of total nodes in flowgraph F are 9.

So, option 1 is correct answer
