Answer:
1. They indicate convergent evolution.
2. They indicate a very close evolutionary relationship.
Explanation:
Convergent evolution is when two species have similar traits that may have evolved at different times, or "independently." So that's a correct answer.
Having a close evolutionary relationship would be both evolving to fit a specific environment in a same way. Meaning that the same factor may have forced them to evolve the same.

The incorrect statement is option (A) the innate defenses of the body apply strictly to external pathogens, while adaptive defenses apply strictly to internal pathogens.
Immunity can be classified into two types namely, the innate immunity and the adaptive immunity. Innate immunity is the first line of defense against the pathogens. It includes the physical and chemical barriers of the immune system along with the action of the phagocytizing cells called the macrophages. Whereas, the adaptive immunity is mediated by the cells of the immune system called the lymphocytes. The B lymphocytes produce antibodies and are responsible for humoral immunity. The T lymphocytes produce the cell mediated immunity with the production of the helper T cell, cytotoxic T cells and attack the pathogens. Innate immune response is comparatively a faster immune response which can be activated by any foreign substance entering the body. Both the defenses work on external and internal pathogens.
