Q1:

In active filter circuits, inductances are avoided mainly because they

A are always associated with some resistance

B are bulky and unsuitable for miniaturisation

C are non-linear in nature

D saturate quickly

ANS:B - are bulky and unsuitable for miniaturisation

In active circuit, Inductors are used by Op-Amp resistors and capacitor instead of simple inductor.
