Concept:
Modernism in architecture emerged mainly during the late 19th and early 20th centuries. It emphasized:
• Simplicity
• Functional design
• Minimal ornamentation
• Use of modern materials such as steel, concrete, and glass
Post-modernism later emerged as a reaction against the strict simplicity of modernism.
Step 1: Analyze Assertion (A).
The statement says modernism started right after the Renaissance and focused on ornamentation.
This is incorrect because:
• Modernism developed much later, mainly in the 20th century.
• Modernism rejected excessive ornamentation.
Architects of modernism followed the principle:
\[
\text{``Form follows function''}
\]
Hence, Assertion (A) is incorrect.
Step 2: Analyze Reason (R).
Post-modernism developed after modernism and criticized the plain and rigid appearance of modernist architecture.
It reintroduced:
• Ornamentation
• Historical references
• Symbolism
Hence, Reason (R) is correct.
Step 3: Choose the correct option.
Assertion (A) is false, but Reason (R) is true.
Therefore, the correct answer is:
\[
{\text{(D) (A) is not correct but (R) is correct}}
\]
