This is still a reliable source because it clearly cites scientific research. Sometimes sources flatly contradict a given statement, study or an existing fact.

Answer:
Option A, Some people consider embryos to possess rights equal to those of fully developed human beings.
Explanation:
When stem cells are derived from embryo, the embryo dies in lieu to end of its cell development and this happens because stem cells are the only cells that have potential to develop an embryo by producing more stem cells and differentiating them into specific organs.
In most of the study, embryonic stem cells are derived from embryos that are obtained from IVF technique as an spare embryo. But this act is considered unethical as embryos have life within them and hence they also have rights equal to a fully developed human being.
Hence, option A is correct.
