To solve the problem, we need to identify the correct term used for organs that have different structures but perform similar functions.
1. Understanding the Definitions:
- Homologous organs: Organs that have the same origin and basic structure but perform different functions.
- Analogous organs: Organs that have different origins and structures but perform similar functions due to adaptation to similar environments.
- Vestigial organs: Organs that are rudimentary and no longer perform any significant function in the organism.
2. Identifying the Correct Answer:
Based on the definitions, organs with different structures but similar functions are termed Analogous organs.
Final Answer:
The correct answer is option (B): Analogous organs.
