Final answer:
All graffiti artists share the ultimate goal of wanting to become famous, as graffiti is a form of public discourse and political expression rather than a pursuit of wealth or a career pivot.
Step-by-step explanation:
The question asks about the ultimate goal shared by all graffiti artists regardless of their background or what they write. Graffiti art, as a form of cultural expression, became notably popular in Western countries during the 1960s. With this context, it is clear that the correct answer is (b) Wanting to become famous. Graffiti is often about making a statement or engaging in public discourse, rather than pursuing goals like becoming a graphic designer, making a lot of money, or simply getting writing out of one's system. Artists like Jean-Michel Basquiat started with graffiti and gained recognition, which sometimes led to significant financial success and fame. Additionally, graffiti is used as a form of political expression and social activism and has been a crucial part of political uprisings, where the artists' intention is often to be heard or to elicit awareness rather than personal enrichment.
