Correct Option: A

From given figure we conclude that first we must find gain in dB at point A in order to calculate the value of K

40 =	A(in db)
	log(5/2)

or

A (dB) = 40 log	5	= 15.9
	2

Now,

20 log	K	|at s=2 = 15.9
	s2

or

K	|at s=2 = 1015.9/20
s2

or
K = 2² × 6·23 = 24·949
Hence alternative (A) is the correct choice.
