Quizplus · Accepted Answer

Organisms selected for loss of genes through reductive evolution often become pathogens or develop dependence on a symbiotic partner's resources.

Additionally, losing non-essential genes frees up resources that can be redirected towards other functions, such as acquiring new ecological niches. Therefore, options B and C are both correct.
