Answer:
b. False. The material, however, must be attributed appropriately.
Step-by-step explanation:
When paraphrasing, we are using our words to convey the main message. Therefore, it is not necessary to use quotation marks but it must be properly cited and attributed. But generally, if you are taking an exact sentence from the original source, it is considered as a quote and quotation marks should be used.
Therefore, in summary, paraphrased sentences from any source do not require quotation marks but should be properly attributed while quotes from original sources must use quotation marks.
