A. A man feels lonely when his company sends him to a new office.
Explanation:
An external conflict refers to an obstacle or struggle that a character faces with an outside or foreign antagonist or situation. In that respect, the conflict does not arise from within the character himself.
In the chosen situation, since his company has sent the man to a new office, he cannot help but having feelings of isolation and desolation because he probably does not know the employees and is alone in the city.
