We need to determine the excretory product of birds and reptiles among the given options.

2. Relevant Concepts

• Birds and reptiles have adapted to conserve water, which is crucial for their survival in various habitats.
• The common excretory products in animals are urea, uric acid, ammonia, and amino acids.

3. Analysis and Detail

• Urea: Typically excreted by mammals; less toxic than ammonia and requires more water for excretion.
• Uric Acid: A solid paste-like substance that requires less water to excrete, making it a suitable option for birds and reptiles.
• Ammonia: Highly toxic and requires a large amount of water to excrete, typically found in aquatic animals.
• Amino Acids: Not a primary excretory product; they are broken down and utilized by the body.

4. Verify and Summarize

Given that birds and reptiles excrete uric acid, which conserves water and is less toxic, the correct answer is:

Final Answer

B. Uric acid
