If the signal flow graph shown in the figure has M number of forward paths P number of individual loops,then

If the signal flow graph shown in the figure has M number of forward paths P number of individual loops,then

A. M=3 ,P=3
B. M=2 ,P=3
C. M=3 ,P=4
D. M=2 ,P=4

Explanatory answer:

Forward paths:
M1=G1G2G3G4
M2=G5G6G7G8

M=2

Individual loops:

P1=G2H2
P2=G3H3
P3=G6H6
P4=G7H7

P=4
