Correct Answer  Option 1 : One
Concept:

The order of a control system is determined by the power of ‘s’ in the denominator of its transfer function.
 The number of openloop poles occurring at origin determines the type of system.
Calculation:
\(G\left( s \right)H\left( s \right) = \frac{K(s+2)}{{s({{s^2} + 2s + 3})}}\)
Type = number of poles at origin = 1
Order = Total number of poles =
