My query is from Tellegen’s theorem in section Useful Theorems in Circuit Analysis of Network Theory

Answer 1

The correct option is (d) all of the mentioned

For explanation I would say: Tellegen’s Theorem is valid for any lumped network. So, Tellegan’s theorem is valid for linear or non-linear networks, passive or active networks and time variant or time invariant networks.
