state how you agree or disagree with the following statement. *A good circuit cannot have internal resistance*

I'm not well read on the subject but I'm guessing they want you to explain what internal resistance is and compare with different functions. From what I understand circuits for appliances such as automatic lights need a lot of internal resistance for the LDR to efficiently work whereas circuits that are just carrying charge to be used by other appliances need as low internal resistance as possible for it to be efficient. Again I am not well informed on the subject so you its probably best you check with someone else

'Good' is not a very helpful choice of word here.

Well internal resistance is unavoidable... yet we can allow for it and make circuits that work and are acceptable... so that's good.

but if reducing internal resistance in a power supply or battery is achievable and cheap enough it'd usually be a 'good' thing to do.

question seems more like it's calling for a philosophical discussion of 'goodness' rather than having a right/wrong answer tbh.

For a circut to experience internal resistance it is dependent on the type we are dealing with and we know that there can not be circuit which is 100% perfect which means there can't also be a 100% good circut either so therefore whether a circut is good or bad it will still experience some form of internal resistance
