You want to know the price of something so you say, ____ ?

1. Interrogative Structure: When asking about the price of something, we typically use the interrogative pronoun "how" to indicate quantity or extent, and "much" to specify an amount or degree.

2. Verb Usage: In English, the verb "is" is used to link the subject (the item being priced) and the predicate (the price). This is because the verb "to be" is commonly used to express existence, identity, or state of being.

3. Order of Words: In English interrogative sentences, the word order is typically inverted compared to declarative sentences. In this case, the subject ("it") comes after the verb ("is").

4. Avoiding Redundancy: Using "How much" alone already implies asking about the price, so there's no need to include additional words like "price" or "cost" in the question.

5. Elimination of Incorrect Options:

- Option ক: "How many is it?" is incorrect because "how many" is used for countable items, not for asking about the price of something.

- Option খ: "How much the price" is grammatically incorrect and redundant. "How much" already implies "the price."

- Option গ: "What is costs" is grammatically incorrect. The correct form would be "What does it cost?" or "What is the cost?"

6. Consistency with Standard Usage: "How much is it?" adheres to standard English grammar and usage for inquiring about the price of something.

Therefore, by following the rules of interrogative structure, verb usage and word order, "How much is it?" is the correct and natural way to ask about the price of something in English.
