Explanation:

The correct answer is option 'B' - "The, the, the".

The word "the" is used to refer to specific or particular nouns, while the word "a" is used to refer to non-specific or general nouns. In this case, we are referring to a specific accident involving the Titanic.

Breaking down the sentence:

The sentence can be broken down into three parts:

1. "The Titanic" - This refers to a specific noun, the ship called the Titanic.

2. "met with" - This is a verb phrase indicating that the Titanic encountered or experienced something.

3. "the accident" - This refers to a specific noun, the accident that the Titanic experienced.

4. "in the Pacific Ocean" - This is a prepositional phrase indicating the location where the accident occurred.

Applying the correct articles:

1. "The" is used before "Titanic" because we are referring to a specific ship, the Titanic.

2. "The" is used before "accident" because we are referring to a specific accident, the one that the Titanic experienced.

3. "The" is used before "Pacific Ocean" because we are referring to a specific location, the Pacific Ocean.

The correct sentence:

Putting it all together, the correct sentence is:

"The Titanic met with the accident in the Pacific Ocean."

This sentence correctly uses the definite article "the" before the specific nouns "Titanic," "accident," and "Pacific Ocean" to indicate that we are referring to specific instances of these nouns.
