He asked me when the next letter would come” বাক্যের direct speech হচ্ছে— ?

The sentence "He asked me when the next letter would come” is an example of indirect speech, which conveys someone's spoken words without quoting them directly. To convert it into direct speech, we usually format it to reflect what the speaker said using quotation marks.

In this case, the correct transformation involves adding a reporting clause that accurately reflects the original question in a manner typical of direct speech. The correct formulation for this transformation would be: “He said to me, ‘When will the next letter come?’”

Now, analyzing the options provided, we see that:

- A) He said to me, – While this option resembles part of a correct transformation, it is incomplete as it doesn't include the quoted question.
- B) He asked to me, – This is incorrect since 'asked' typically doesn’t use 'to.'
- C) He said to me, – This option is similar to A but is also incomplete without the question. However, it is the least problematic as it uses 'said,' which is appropriate for reporting without direct questioning.
- D) He said me.. – This is grammatically incorrect because it lacks a proper construction.

Thus, while C is still technically incomplete as it stands, it is the most acceptable choice since it uses the correct verb 'said.' In a more complete direct speech format, we would need to add the direct quotation to fully convey the meaning.
