B. mass communication
Explanation:
John O'Sullivan coined the term "Manifest Destiny" to explain what he saw as the United States' God-appointed obligation to spread across the continent of North America and lead the world by example of its values. O'Sullivan was editor of the Democratic Review and New York Morning News when editorials put out reasons for annexing Texas and the Oregon Territory in both newspapers (in July 1845). In the years that followed, U.S. public policy generally adopted the kind of regional ambitions defined by O'Sullivan, though not always with his same religious philosophy throughout mind.
