What is incorrect about this orbital diagram?

• Both arrows in the filled 2p box should be pointing the same direction

• There is nothing incorrect with this diagram

• In the there should only be 1 arrow in the first 2p box and one in the 2nd 2p box

• All the arrows should be pointing the same direction.
