Change into Indirect Speech :
He said, "I bought these pearls for my mother".

Question

Accepted Answer

Here's the explanation:

**Why Option 4 is correct: "He said that he had bought these pearls for his mother."**

This option correctly transforms the direct speech into indirect speech by following the rules of tense and pronoun changes. Here's a breakdown:

*   **Reporting Verb:** The reporting verb "said" remains in the past tense.
*   **Conjunction:** The conjunction "that" is correctly introduced to link the reporting clause ("He said") to the reported clause.
*   **Pronoun Change:** The pronoun "I" changes to "he" to reflect that the speaker is reporting what someone else said.
*   **Tense Change:** The verb "bought" (simple past tense) in the direct speech changes to "had bought" (past perfect tense) in the indirect speech. This is because when the reporting verb is in the past tense, the tense of the verb in the reported speech usually moves one step back into the past.
*   **Demonstrative Change:** The demonstrative "these" changes to "those" (although this change is not reflected in the options, the tense change is the most important factor here).
*   **Possessive Adjective Change:** The possessive adjective "my" changes to "his" to reflect the change in pronoun.

**Why the other options are incorrect:**

*   **Option 1: "He said he buy pearls for his mother."** This is incorrect because it doesn't change the tense of the verb "buy." The verb should be in the past tense since the reporting verb "said" is in the past tense. It also omits the necessary conjunction "that".

*   **Option 2: "He said will buy pearls for his mother."** This is incorrect because it uses the future tense "will buy" without any proper tense shift from the original statement. It also omits the necessary conjunction "that".

*   **Option 3: "He said that he will bought these pearls for his mother."** This is incorrect because it uses "will bought," which is grammatically incorrect. "Will" is a modal verb and should be followed by the base form of the verb. Also, the tense shift is not done correctly.
