[amp_mcq option1=”a” option2=”an” option3=”the” option4=”no article” correct=”option4″]
The correct answer is D. no article.
The word “mistake” is a non-count noun, which means it does not have a plural form and cannot be preceded by an article. For example, you would not say “I have made a mistake” or “I have made two mistakes.” Instead, you would say “I have made a mistake” or “I have made mistakes.”
In this case, the speaker is not referring to a specific mistake, but rather to mistakes in general. Therefore, the article “a” or “an” would not be appropriate. The article “the” would also not be appropriate, because the speaker is not referring to a specific mistake that has already been mentioned.
Therefore, the correct answer is D. no article.
