Knowing Minato he'll always use counter 1 but this is another OP counter with which Minato is so OP that it's like Tobi's ghost mode but even dangerous.
For this Minato needs three shadow clones and he's good to go. He uses the Jikukan Barrier i.e. FTG barrier for this one.
Minato stands in the middle while his his shadow clones surround him in a "Y"
formation and all of them use the FTG barrier like these ones
And we know that how big the barrier can be, I mean Juubi's TBB is greater than any and every attack Nagato has to offer is Minato soloed it like it was nothing
Now in the Y
formation the clones make the barrier covering 120 degrees each and hence 360 degrees are covered while the real one does in the upwards direction so the top is covered as well. with this Minato has essentially created a black hole and only way to break this defense is to attack from beneath for which Minato can just use another shadow clone wcho activates the barrier on down side which forms the ultimate defense.
So once this is done all the incoming attack or BT,ST all go to the sea or Amegakure where Minato could just drop a kunai Lol Nothing works when Minato pulls this, it is greater than Tobi's perfect Ghost Mode
