Step-by-step explanation:
The term blaxploitation was coined by Junius Griffin when he was head of the Los Angeles NAACP in the early 1970s. Blaxploitation is a film genre that emerged from the United States, featuring African-American actors in lead roles and often having storylines that were both thrilling and sensational, with the intent of attracting an urban, African-American audience.
Despite its name, the genre played a significant role in providing African-American actors with greater opportunities in Hollywood, although it also faced criticism for stereotypical characters and plotlines. It is important to note that the other individuals listed as options in the question, such as Mario Van Peebles, Quentin Tarantino, and Spike Lee, are filmmakers who have been influenced by or have commented on the blaxploitation genre, rather than being the originators of the term.
