Option 4 : Grounded Y to grounded Y

Zero sequence network of transformer:

In a star connection without ground, the neutral path is open-circuited, hence zero-sequence current is absent in this connection.
In a star connection with the ground, the neutral path is short-circuited, hence zero-sequence current can flow in this connection.
In the delta connection, the circuit provides no return path, hence the zero sequence currents cannot flow in delta connected transformer.
