Change the following direct speech sentence into the correct indirect speech form by selecting the appropriate option: He said, “Let it rain I have to go.”

Introduction / Context:
This question tests knowledge of converting direct speech into indirect or reported speech. The original sentence expresses determination: the speaker says that even if it rains, he still has to go. When transforming such sentences, we must preserve the speaker attitude and meaning, while changing pronouns, tenses, and structure according to the rules of reported speech. The correct indirect form should show that he remained firm and unaffected by the possibility of rain.

Given Data / Assumptions:

• Direct speech: He said, “Let it rain I have to go.”
• The sentence contains an imperative like “let it rain” and a statement “I have to go”.
• The reporting verb is “said”, and we must find the best indirect rendering among the options.
• The intention is to express the speaker strong resolve rather than fear or reluctance.

Concept / Approach:
In reported speech, we do not always reproduce exact words like “let it rain”, but we convey the sense. The speaker is essentially saying that rain will not stop him. A suitable reporting verb for such insistence or firm attitude is “persisted” or “insisted”. The clause should show that he does not care about the rain and still has to go. Among the options, only option A captures both ideas: indifference to the rain, and obligation or determination to go. The tense shifts from present “do not care” and “have to go” to past “did not care” and “had to go” in line with standard back shifting when the reporting verb is in the past.

Step-by-Step Solution:

Verification / Alternative check:
We can check by reimagining the direct speech that might produce option A. If we start from “He persisted that he did not care for the rain and he had to go”, a possible direct form could be “He said, ‘I do not care for the rain, I have to go’.” That is very close in meaning to “Let it rain I have to go”. The essential message of determination against weather conditions is preserved. The other options either distort the meaning or use incorrect grammar. For instance, option B uses “can't stop him to go out”, which is not a correct pattern; it should be “stop him from going out”. Option C incorrectly uses “exclaimed” and mixes tenses. Option D reverses the meaning by suggesting he cannot go because of rain. Therefore, option A is the only acceptable transformation.

Why Other Options Are Wrong:

• Option B: “He said that rain can't stop him to go out” has faulty grammar (“stop him to go” is incorrect) and does not reflect the exact tone of determination in a natural way.
• Option C: “He exclaimed that let it rain but he will go” is awkward. The phrase “that let it rain” is not normal reported speech, and the tense “will go” is not properly back shifted.
• Option D: “He said that he can't go just because it is raining” actually reverses the original meaning by suggesting he cannot go due to rain, whereas the direct sentence indicates he will go despite rain.

Common Pitfalls:
In reported speech questions, candidates sometimes focus only on mechanical rules of tense change and ignore the deeper meaning. As a result, they may pick an option that is grammatically polished but semantically wrong. Another pitfall is not noticing that certain phrases in direct speech, such as “let it rain”, cannot be copied directly into indirect speech, and instead must be paraphrased. The safe approach is always to first paraphrase the direct sentence in your own words, then look for the option that best matches that paraphrase with correct grammar and tense.

Final Answer:
The correct indirect speech form is “He persisted that he did not care for the rain and he had to go.”
