Select the option that correctly expresses the given sentence in direct speech.

He mentioned to her that the movie they had watched the previous week was not as thrilling as he had expected it to be.

The correct answer is: He said to her, “The movie we watched last week was not as thrilling as I expected it to be.”

Step-by-step explanation:

To convert a sentence from Indirect Speech to Direct Speech, follow these grammatical rules:
1. Reporting Verb and Conjunction: The reporting clause "He mentioned to her that" becomes "He said to her, “...”" and the conjunction "that" is removed.
2. Pronoun Conversion:
- The third-person pronoun "they" in indirect speech converts back to the first-person plural pronoun "we" in direct speech.
- The third-person pronoun "he" converts back to the first-person pronoun "I".
3. Tense Conversion:
- Past perfect tense ("had watched") changes back to simple past tense ("watched").
- Past perfect tense ("had expected") changes back to simple past tense ("expected").
4. Adverbial/Time Expressions: The phrase "the previous week" in indirect speech changes back to "last week" in direct speech.

Combining these changes gives the correct direct speech sentence:
He said to her, “The movie we watched last week was not as thrilling as I expected it to be.”
