The correct answer is: A. a, a
Wheat is a type of grain that is used to make flour, bread, and other baked goods. It is a whole grain, which means that it contains all three parts of the grain: the bran, the germ, and the endosperm. Whole grains are a good source of fiber, vitamins, and minerals.
In the sentence "Wheat is a wholesome meal," the word "a" is used before the noun "wheat" because wheat is a specific type of grain. The word "a" is used before singular nouns that refer to specific things.
The word "a" is also used before the noun "meal" because "meal" is a general noun that refers to any type of food. General nouns are not capitalized unless they are the first word in a sentence.
The answer B. no article, a is incorrect because the word "a" is needed before the noun "wheat."
The answer C. a, an is incorrect because the word "an" is used before singular nouns that begin with a vowel sound. The word "wheat" begins with a consonant sound, so the word "a" should be used.
The answer D. an, the is incorrect because the word "an" is used before singular nouns that begin with a vowel sound. The word "the" is used before specific nouns that have been previously mentioned. In the sentence "Wheat is a wholesome meal," the word "wheat" is not a specific noun that has been previously mentioned, so the word "the" should not be used.
