Q1:

In a reactance function

A all poles are simple

B all poles and zeros are simple

C all poles and zeros are simple and lie on jω axis only

D all poles and zeros lie on negative real axis

ANS:C - all poles and zeros are simple and lie on jω axis only

Only then the network has only L and C. If poles and zeros are not on jω axis, resistance will be there.
