The answer requires looking at the meaning of the words 'theory' and 'law'. The formal definition of a theory is that it is a comprehensive explanation of a observed phenomenon supported by a lot of evidence. Law is a fact that is bound to be true in nature, example Newton's second law. However, a theory is subjected to continuous refinements based on the several new findings that happen with time. These refinements make the theory appear incomplete. As with the theory of evolution, a lot of research work is being put to understand the complex phenomenon of genetic inheritance of traits of behaviour. Unless there are evidences from nature for all the aspects of evolution in theory, it'll remain a theory and not become a law.
Answer is A) Yes, if scientists decide that enough evidence supports the theory.
I think the answer should be medulla oblongata or foramen magnum.
The major nerves that leave brain should form a thick cord in the brain stem that called medulla oblongata. Medulla oblongata will pass a big hole in the base of the skull that called foramen magnum. Depends on what part the question asked(bone or tissue), it probably between those two options.

Answer:
Reciprocal altruism is one of the altruism behaviors in which an individual organism helps in increasing the fitness of another organism by reducing the fitness of itself temporarily in expectation of the same behavior from another organism in the future later.
It takes place in the same set of organism partners which is a continuous interaction ion in stable groups of organisms.
Thus, the correct answer would be - an ongoing interaction in the same set of partners.
