(a) number of poles

Explanation:

If the number of poles are greater than the number of poles in an G (s) then the number of root locus branches is equal to the number of poles

If number of zero are greater than number of poles then the number of branches of root locus will be equal to the number of zero.

If number of poles and number of zero both are same then the number of root locus branches are equal to the = number of poles=number of zero

Here in question it is given that number of poles are greater than the number of zero so root locus branches will be equal to the numb er of poles

So option (a) will be the correct option
