Plagiarism is avoided by a) using only your own words b) summarizing instead of quoting c) citing all sources d) using only credible sources

The correct answer is option A) using only your own words.

Explanation:

Plagiarism is an act of fraud where the text or ideas of other people or sources are stolen to make them look as your own.

The correct way to avoid plagiarism is to use your own words.

While it is convenient for your work to look for other sources of information, it is best that you can interpret those sources and be able to transmit them in your own words and with your own analysis and ideas.

This way you will avoid fraud.
