Answer: The most commonly used articles in English are "a," "an," and "the."
Step-by-step explanation:
1. "A" is used before a singular noun that begins with a consonant sound. For example, "I saw a dog in the park."
2. "An" is used before a singular noun that begins with a vowel sound. For example, "She is an excellent dancer."
3. "The" is used before both singular and plural nouns when we want to refer to something specific or known. For example, "I saw the dog that was barking."
On the other hand, "to" is a preposition, not an article. It is used to indicate direction, purpose, or time. For example, "I am going to the store" or "I gave the book to my friend."
Lastly, "very" is an adverb used to intensify or emphasize the meaning of an adjective or adverb. For example, "He is very tall" or "She ran very quickly."
So, the correct answers for the most commonly used articles are "a," "an," and "the."
