An AC coupled path will have a capacitor in series in the path. Only AC will pass through & any DC levels will be blocked.
In a DC coupled path, everything flows through exactly as it comes in, including the DC levels of course.
I have a lot of doubts here with out knowing more the answers here are futile to the best of my knowledge
In general if there is a Capacitor in parallel to the supply line it is a way of coupling the entire DC voltage into the other path to which the capacitor is connected in parallel
In that way you can easily discern a DC circuit almost all capacitors will be parallely fed to the ground to remove any noisy ripples in the op
But this is a poor way of discerning between AC and DC circuit in hybrid circuits
