The correct answer is C. Reliability.
Explanation
When conducting an investigation, it is necessary to argue through sources that help the author to check his hypothesis on a specific topic. For this purpose, the author can access primary, secondary, and tertiary sources that are categorized depending on their level of specificity and the origin of the information found there.
In the first place, the primary sources are those that provide very reliable information on a specific event such as diaries, interviews, speeches, letters, chronicles, research, objects, among others; Those are characterized by being completely related to a specific time and that some person of the time have been the one who produced them.
Secondary sources are encyclopedias, dictionaries, reviews, texts, biographies, among others, these are characterized by taking information from different primary sources and briefly summarizing it taking into account their different points of view.
Third, there are bibliographies and information catalogs that present a guide to what should be consulted if you want to research a topic, they are a very general view of a topic and are usually the starting point to go from the general to the specific.
Additionally, to establish the reliability of a source, it is necessary to know how current it is, when it was last updated because science tends to evolve rapidly, so the information that a few years ago was believed to be true could have been denied or confirmed. Therefore, it is necessary to review the most current bibliography in order to carry out a complete and effective investigative work. According to the above, the correct answer is C. Reliability.
