Answer:


In this sentence, the correct answer is option 'A' - no article needed. Let's understand why:

Definite and indefinite articles:
In English, articles are used to indicate whether a noun refers to a specific or non-specific item. There are two types of articles: definite (the) and indefinite (a/an).

The definite article 'the' is used when we are referring to a specific item or items that both the speaker and the listener are familiar with. For example, "I saw the dog in the park."

The indefinite articles 'a' and 'an' are used when we are referring to a non-specific item or one that has not been mentioned before. 'A' is used before words that start with consonant sounds, while 'an' is used before words that start with vowel sounds. For example, "I saw a car on the road."


In the given sentence, "We're having fish for _____ dinner," we do not need to use any article. This is because the sentence is referring to a general type of meal, rather than a specific instance of fish. It is not indicating a specific fish or a specific dinner that is known to both the speaker and the listener.

Using the indefinite article 'a' would imply that they are having one specific fish for dinner, which is not the intended meaning.

Using the definite article 'the' would imply that there is a specific fish or dinner that both the speaker and the listener are aware of, which is also not the intended meaning.

Therefore, in this case, no article is needed, and the correct answer is option 'A' - no article needed.
