How to decide which swap is suitable?

The question is to calculate the notional principal of a Swap and there are 3 swap to choose.

Use which swap depends on the duration of the swap or other condition ?

Thx

They want you to choose the swap with the smallest notional amount.

I understand, thx S2000Magician

You’re quite welcome.

…not sure if the question was for real nor the answer was for real.

The answer was for real.

S2000 does not joke with <50 days to go.

That means: use the swap with the highest duration?

Yes: the highest net duration.
