Well what have you learned about this so far?The Loop gain and phase plot a control loop is shown below. Please comment on the
stability of the system.
Also, comment on the system stability if the gain (alone) of the system changes significantly.

Hi Thanks forWell what have you learned about this so far?
What do you know about the gain and phase relationship for stability?
Actually though you are supposed to show your first attempt to solve this in the Homework section.

No, your conclusion is not correct. The concepts of phase and gain margins cannot be applied because the loop gain exhibits three crossings of the zero deg line. As I have written in my answer#3 you have to apply the FULL Nyquist criterion.So the overall system is unstable as GM is changing insignificantly.

There is not much to explain.Hello,
Thanks for reply !
Could you please explain about at some extent ?
The reason for saying stable system as i see using bode diagram it is unstable system.
Thanks in advance !
