The correct answer is (A).
The phrase “with a view to” means “in order to” or “with the intention of.” In this case, the student is working hard in order to attain good marks in the examination.
The phrase “with a view of” is also correct, but it is less common.
The phrases “with a view for” and “No improvement” are both incorrect. The phrase “with a view for” is not idiomatic, and the phrase “No improvement” does not provide any additional information.
Here are some examples of how the phrase “with a view to” can be used:
- I am going to the store with a view to buying some milk.
- I am taking this course with a view to getting a better job.
- I am writing this letter with a view to resolving the issue.
