The correct answer is B. Safety needs
Step-by-step explanation:
In Maslow's need theory there are five different types of needs, this includes psychological needs, safety needs, love, and belonging needs, esteem needs and self-actualization needs. In the case of safety needs, this includes the need for feeling safe, which means not to feel vulnerable and the feel of stability that implies knowing important aspects will not change.
In the case of Milo, his concern reflects a desire to satisfy his safety needs, because in his case he wants to move to a different country because he feels vulnerable or unsafe due to the political unrest and street violence which is related to safety needs.
