Find the ultimate gain and frequency for a proportional controller in the case of a process having the transfer function Gp(s) = 1/(4s + 1)(2s + 1)(s + 1).

W = √(7/8), Kc = 45/4

W = √(7/6), Kc = 46/3

W = 1/√14, Kc = 45/7√14

W = 1, Kc = 13

W = √(7/8), Kc = 45/4

W = √(7/6), Kc = 46/3

W = 1/√14, Kc = 45/7√14

W = 1, Kc = 13
