As we have already discussed in Theories of Evolution: Lamarckism -

Lamarckism is also called ‘Theory of Inheritance’.According to him, the constant use of organs makes them more efficient and less or no use of organs brings about degeneration. Such acquired characters are inherited through generations. According to this theory, a Nobel laureate has a sharp brain due to greater use of it but this character must be inherited to his progeny. Thus, it cannot explain the occurrence of the weak progeny of a Nobel Laureate hence, the correct option is (a).
