According to Lamarck, the characteristics which are developed during the lifetime of an individual due to use and disuse of organs are called as:
Correct answer: C. acquired characters
- A. prominent characters
- B. biological characters
- C. acquired characters
- D. physical characters
Explanation
Lamarck held that organs strengthened by use or weakened by disuse during an individual's life produce acquired characters, which he believed were passed to offspring. Later genetics showed such characters are not inherited, which is the main reason Lamarckism was replaced by Darwin's natural selection.

About Lamarckism
Lamarckism explains evolution through environmental influence, use and disuse of organs, and the inheritance of acquired characteristics. It differs from Darwinian natural selection because Lamarck proposed that organisms develop useful traits during their lifetime and pass them on, a view not supported by modern genetics.
