The loop transfer function of a negative feedback system is \(G\left( s \right)H\left( s \right) = \frac{1}{{s\left( {s - 2} \right)}}\). The Nyquist plot for the above system
1

2
encircles (-1 + j0) point once in the counter clockwise direction
3
does not encircle (-1 + j0) point
4
encircles (-1 + j0) point twice in the counter clockwise direction
