As you have not specified any specific question so I am answering according to the HomeworkLib guidelines please cooperate.
Answer 8
Option b is correct
A proportional controller (Kp) will have the effect of reducing the rise time and will reduce but never eliminate the steady-state error.
Answer 9
Option d is correct
As more ki will lead to less damping i.e shorter peaks so damping will reduce with decrease in ess to step input.
