Concept:
Poster design occupies a unique position between fine art and commercial communication. Throughout the history of graphic design, posters have been used not only for advertising and public communication but also as artistic expressions.
A distinction gradually developed between:
• Commercial posters used for promotion and advertising
• Artistic posters created with aesthetic and creative intent
This distinction helped establish poster design as an important field within graphic design.
Step 1: Understanding Assertion (A).
Assertion (A) states that the distinction between commercial posters and artistic posters helped:
• Establish posters as an art form
• Increase the importance of poster design in graphic design
This statement is correct.
Historically:
• Posters were initially viewed mainly as advertising tools
• Later, artists and designers elevated poster-making into an artistic discipline
• Artistic poster movements emerged in Europe and elsewhere
Thus, the distinction became important in design history.
Step 2: Understanding Reason (R).
Reason (R) states that poster design is an important part of graphic design but many thinkers do not fully consider graphic design as pure fine art.
This statement is also correct because:
• Graphic design often serves commercial purposes
• Fine art traditionally focuses on personal artistic expression
• Some critics separate functional design from fine arts
This debate contributed to the distinction between artistic and commercial posters.
Step 3: Checking whether Reason explains Assertion.
The Reason directly explains why the distinction became necessary.
Because graphic design was often viewed as commercial rather than artistic:
• Designers differentiated artistic posters from commercial posters
• This helped posters gain artistic recognition
• Poster design earned importance in visual communication studies
Therefore, Reason correctly explains Assertion.
Final Conclusion:
Both Assertion and Reason are correct, and Reason correctly explains Assertion.
Therefore, the correct option is:
\[
\boxed{(1)}
