Answer is Right!
Answer is Wrong!
The correct answer is: D. no article
The word “concert” is a countable noun, which means it can be used with a number. In this case, the speaker is not specifying which concert they are going to, so they do not need to use an article.
If the speaker were specifying which concert they were going to, they would use an article. For example, they might say:
The article “a” is used before singular countable nouns that are not specific. The article “the” is used before singular countable nouns that are specific.
