Step 1: Understanding the Concept:
This question tests the formation of question tags. A question tag is a short question at the end of a statement.
Step 2: Key Formula or Approach:
The rules for forming a question tag are:
1. If the main statement is positive, the question tag is negative, and vice versa.
2. Use the same auxiliary verb as in the statement. If there is no auxiliary, use 'do', 'does', or 'did'.
3. Use the same subject pronoun as in the statement.
Step 3: Detailed Explanation:
The statement is "Rajesh is still shouting".
1. Positive/Negative: The statement is positive. So, the tag must be negative.
2. Auxiliary Verb: The auxiliary verb is 'is'. The negative form is 'is not', contracted to 'isn't'.
3. Subject Pronoun: The subject is 'Rajesh', which is a male name, so the pronoun is 'he'.
Combining these parts, the correct question tag is "isn't he?".
The full sentence is: "Rajesh is still shouting, isn't he?"
Step 4: Final Answer:
Following the rules for question tags, the correct option is (D) isn't he.
