Will . . . . . . . . dog bite? A. a B. an C. the D. none of the above

The article “a” is used before singular common nouns that refer to a general or unspecified thing. For example, “I saw a dog.”

The article “an” is used before singular common nouns that begin with a vowel sound. For example, “I saw an apple.”

The article “the” is used before singular common nouns that refer to a specific thing. For example, “I saw the dog that bit me.”

In this case, we are not referring to a specific dog, so we do not need to use an article.
