Mcdonald's is the proper noun. Normally the proper noun is a name of something or someone, so Mcdonald's would be the proper noun.
The correct options are "premeditated invasion" and "grave danger".
We refer to words such as "invasion" and "danger" as loaded words because of how immediately they stick on our mind as we hear or read them inside a phrase. This occurs because the connotation and literal meaning of them is without a doubt negative, and represent very quickly the sense of a harming threat.
