Step 1: Understanding sentence transformation.
An assertive sentence makes a statement (affirmative or negative). To convert an interrogative sentence (“Has anyone seen the wind?”) into an assertive one, we remove the question form and state it directly.
Step 2: Change of structure.
Interrogative form: “Has anyone seen the wind?”
Assertive form: “No one has seen the wind.”
Step 3: Analyze the options.
- (a) No one has seen the wind: Correct assertive statement.
- (b) Wind has no one seen: Incorrect word order.
- (c) Seen no one wind: Grammatically wrong.
- (d) Has seen no one wind: Incorrect structure.
Step 4: Grammar check.
The subject “No one” correctly replaces “Anyone” in the assertive transformation while keeping the verb tense (“has seen”) unchanged.
Step 5: Conclusion.
Hence, the correct assertive form is “No one has seen the wind.”
