The correct answer is E. Summarizing information from a source and including it to support my ideas and citing the source.
Explanation:
To avoid plagiarism it is necessary to correctly cite sources; this is mandatory if you took the exact words of a source, summarized information of a source, or used your own words to express the ideas of someone else because in all these cases you are using ideas that are not your own and you need to acknowledge authorship.
In this context, the only situation that is not an example of plagiarism (presenting other's ideas as your own) is "Summarizing information from a source and including it to support my ideas and citing the source" because this is the only situation in which the source was cited, which acknowledges the original author and prevents plagiarism.
