Explanation:

• Biogeography studies species' geographic distribution, not amino acid sequences.
• Development focuses on organismal growth/development, not molecular sequences.
• Molecular evidence involves analyzing molecules (like proteins/DNA) to show evolutionary relationships, which matches amino acid sequence analysis.
• Anatomical features are physical structures, not molecular sequences.

Answer:

C. molecular evidence
