Answer: Using single quotation marks within double quotation marks
Explanation: The quotations serve to denote a text as it is pronounced originally, that is, not paraphrase or persuasion. Usually, within the sentence, the part of the text that is originally stated is separated from the rest of the sentence using the quotation marks. When quotation should be made within the existing quotation, then for a new quotation, we use single quotation marks, within the existing quotation for which double quotation marks are used.
