The correct answer is: A. Traits acquired during life are passed on to offspring.
Lamarck’s theory, known as Lamarckism, proposed that organisms could pass on traits that they acquired during their lifetime to their descendants. For example, he believed that if an organism changed in response to its environment (like a giraffe stretching its neck to reach higher leaves), those changes would then be inherited by its offspring. This idea contrasts with Darwin’s theory of natural selection, where traits are passed based on genetic inheritance rather than acquired characteristics.
