Answer is Right!
Answer is Wrong!
The correct answer is D. no article.
Water is a common noun, which means it does not refer to a specific thing. Common nouns are not preceded by articles.
A and an are indefinite articles. They are used to refer to a general thing or person. For example, “I saw a bird.” or “I met an old man.”
The is a definite article. It is used to refer to a specific thing or person. For example, “I saw the bird that was eating my seeds.” or “I met the old man who lives next door.”
In the sentence “Water is necessary for life,” water is not referring to a specific thing or person. It is referring to water in general. Therefore, no article is needed.
