Change to Direct Speech. Choose the correct option :
He asked his father when the next letter would come.

Question

Accepted Answer

Option 4, "He said, 'father, when will the next letter come ?'" is the correct direct speech conversion because:

*   **Correct Question Formation:** The original indirect speech is a question about when the next letter would come. Direct speech needs to reflect this as a direct question. Option 4 correctly uses "when will the next letter come?" which is a direct question.

*   **Reporting Verb and Quotation Marks:** Direct speech requires a reporting verb (like "said") and the actual spoken words enclosed in quotation marks. Option 4 correctly uses "He said" as the reporting verb and encloses the question within quotation marks.

*   **Tense Change:** The indirect speech uses "would come," which is the past form of "will come." Direct speech reverts to the original tense, so "will come" is correct in Option 4.

*   **Addressing the Father:** The original sentence implies the question is directed at the father. Option 4 explicitly includes "father," making it clear who is being addressed. The comma after "father" is also grammatically correct in direct address.

Now, let's examine why the other options are incorrect:

*   **Option 1: He asked his father, "when would the next letter go ?"** This is incorrect because "when would the next letter go?" doesn't accurately reflect the meaning of the original indirect speech. The original question is about *when* the letter will *arrive*, not when it will *be sent*. Also, "go" is not the correct verb to use in this context.

*   **Option 2: He told father when, "the next letter will came."** This is incorrect for several reasons. First, "He told father when" doesn't make sense in the context of a question. Second, "will came" is grammatically incorrect; it should be "will come." Third, the sentence structure is awkward and doesn't properly represent a direct question.

*   **Option 3: He enquired from his father, "when the next letter would come ?"** This is incorrect because while "enquired from his father" is acceptable, the quoted part "when the next letter would come?" is still in indirect speech form. Direct speech requires the future tense "will come," not the conditional "would come." Also, the question mark is misplaced; it should be inside the quotation marks.
