Answer:
peer-reviewed journal.
Explanation:
When conducting scientific research, it is essential to pay attention to the source where the research will be carried out, so the most reliable option is to search in peer review journals, which are scientific journals reviewed by specialists on a given subject.
Therefore, this research source will be more reliable, since this article was reviewed by a council that guaranteed the necessary reliability for publication.
It is not advisable to use a wiki, internet or news flash for scientific research purposes, as these sources have not been reviewed and may have been written by anyone without scientific precedents.
