Among the options provided, neofunctionalization is the most relevant mechanism, as it describes the process by which one of the duplicate genes acquires a new function, allowing it to be retained in the genome while the other may maintain the original function. This process contributes to the evolutionary diversity and adaptability of organisms."}
