In this grammar question on reported speech, you must choose the correct Indirect Speech form of the sentence: "Rohit said, 'I take a bath daily with cold water.'"

Introduction / Context:
This multiple choice question checks your ability to convert a habitual present tense statement from Direct Speech into Indirect Speech. The given sentence is: Rohit said, "I take a bath daily with cold water." You must decide how the simple present tense and the first person pronoun I should change after a past reporting verb. The main focus is on tense backshift and appropriate pronoun substitution in reported speech.

Given Data / Assumptions:

- Reporting verb: said, which is in the past tense. - Reported clause: I take a bath daily with cold water. - The speaker is Rohit, referring to himself as I. - The sentence describes a habitual action: take a bath daily.

Concept / Approach:
When the reporting verb is in the past tense, a simple present tense in the reported clause usually changes to simple past in indirect speech. Therefore take becomes took. Since the speaker is Rohit, the pronoun I changes to he in the reported sentence. Because the sentence talks about a habitual action at the time of speaking, the simple past took a bath daily correctly reports what he said. We introduce the reported clause with that after said, although in everyday usage that may be omitted in speech.

Step-by-Step Solution:

Verification / Alternative check:
To verify the correctness, reverse the process. From Rohit said that he took a bath daily with cold water, you remove that, change he took to I take, and keep the rest of the sentence the same. This gives Rohit said, "I take a bath daily with cold water." which is the original sentence. This back conversion confirms that the chosen indirect speech sentence is accurate.

Why Other Options Are Wrong:
Option A mixes says with were taking, which is grammatically wrong and changes the tense to a continuous form. Option B uses a highly unnatural and incorrect tense combination has had been taking. Option C keeps the verb is taking in present continuous instead of shifting the present simple take to a past form. Option E uses used to take, which introduces the idea that the habit existed only in the past and may not continue, changing the meaning. Option D, however, correctly shifts the tense and pronoun while preserving the original sense of a habitual action.

Common Pitfalls:
Many students confuse habitual present with present continuous and create incorrect forms like is taking. Others overcomplicate tense changes by inserting unnecessary perfect or continuous aspects. Remember the standard guideline: when the reporting verb is in the past, simple present usually changes to simple past. Also be careful to change I to he or she according to the speaker and to keep adverbs such as daily and with cold water unchanged unless there is a clear reason to modify them.

Final Answer:
The correct reported speech sentence is Rohit said that he took a bath daily with cold water.
