Answer:
D.the duty of obedience
Explanation:
Largo has breached the duty of obedience because he was given a very simple instruction, and still he did not followed it. He was simply asked not to sign contracts on his boss behalf on certain days.
The duty of performance would be breached if a more complictad task, with guidelines and standards, had not been completed.
And the duty of loyalty has more to do with more personal or important decisions.
