Explanation

Impact factor, citation index and h-index measure the quality and influence of research articles, which is statements 2, 3 and 5.

Impact factor rates a journal by the average citations its recent articles receive.

Citation index counts how often an article is cited, reflecting its scholarly influence.

The h-index balances the number of papers against the citations each receives, gauging sustained impact.

The mere number of research articles is a measure of quantity, not quality.

Frequency of publication reflects output rate, not the merit of the work.
