Based on the information provided, the options that apply to why the article can be regarded as credible and reliable are:
- It is likely that the article was peer-reviewed as it was published in an academic journal.
- It was published recently in 2020, so the information will be current and up to date.
- It is a research article; the information will be reported objectively with sufficient evidence and reference to other authorities.
The option stating "The authors are not affiliated with a university in the Netherlands" does not inherently contribute to the credibility or reliability of the article, as the credibility of research is more connected to the peer review process, the recency of the publication, and the nature of the research itself rather than the authors' affiliations being outside of a specific country.
