Answer: Deliver the message in person.
Step-by-step explanation:
No one ever wants to hear bad news and this is why it is important that it is delivered in the best way possible because you do not know how stable the person could be.
For this reason, more often than not, it is better to deliver bad news in person because it can add a personal touch to it that can go a long way in alleviating the stress that the person will feel at that moment.
Delivering bad news in person can also give one a chance to keep the bad news under wraps for a season and also to be able to discuss with the intended recipient any way that can be used to get past the bad news away from the presence of prying eyes.
There are quite some Advantages to doing this ( and some disadvantages as well) but of all the listed options, this is by far the best.
