a.

To count the number of statements in the program

b.

To count the number of branches in the control graph

c.

To calculate the number of linearly-independent paths in the control graph

d.

To calculate the number of nodes in the control graph

Posted under Software Testing Software Engineering

Answer: (c).To calculate the number of linearly-independent paths in the control graph Explanation:McCabe's cyclomatic complexity metric is used to calculate the number of linearly-independent paths in the control graph. It is a basis set, which is a maximal linearly-independent set of paths through a graph.
