A doctor and a bus driver both love the same woman, Sana. The bus driver leaves for a week long trip and gives Sana seven apples before he goes. Why does he do this?

Introduction / Context:
This riddle mixes simple romance with a well known English proverb to create a playful logical puzzle. Instead of needing any mathematical calculation, you simply need to connect the details of the story about Sana, the doctor and the bus driver with a common saying about health. Such questions are popular in verbal reasoning and English comprehension sections because they test whether candidates can recall idioms and use them logically in a short scenario.

Given Data / Assumptions:
- Both a doctor and a bus driver are in love with Sana. - The bus driver will be away for seven days on a trip. - Before leaving, he gives Sana seven apples. - The number of apples matches the number of days he will be away. - There is no mention of any other special meaning in the story.

Concept / Approach:
The central idea is the proverb that many students learn in school: An apple a day keeps the doctor away. The bus driver knows that he has competition from the doctor. By giving Sana one apple for each day he is away, he is playfully trying to ensure that the doctor stays away from her. The puzzle therefore tests both your knowledge of common English proverbs and your ability to see how they can be applied in a story. It is not about nutrition or real romance, but about wordplay.

Step-by-Step Solution:
1. Notice that there are seven apples and the bus driver will be away for seven days. 2. Recall any proverb that connects apples with days and health. 3. Remember the line An apple a day keeps the doctor away. 4. Realise that the doctor is the rival in this love story. 5. Conclude that the bus driver wants Sana to eat one apple each day so that the doctor is kept away from her.

Verification / Alternative check:
To check the logic, imagine removing the proverb from your mind. The story with seven apples then becomes a weak coincidence. Nothing else in the text explains exactly why apples are chosen instead of flowers, chocolates or any other gift. Once you remember the proverb, the number seven suddenly makes sense, because it allows Sana to eat one apple per day for the entire week. This strong connection confirms that the intended explanation must be related to the saying An apple a day keeps the doctor away.

Why Other Options Are Wrong:
Option B and option C describe reasonable but generic reasons for giving apples, such as taste or health, but they do not use the clever wordplay involving the doctor. Option D talks about seven days of love, which may sound romantic but ignores the clear link to a proverb. Option E mentions impressing her family, which has no support in the question. Only option A captures both the exact wording of the proverb and the rivalry between the doctor and the bus driver.

Common Pitfalls:
A frequent mistake is to answer that apples are simply healthy or that seven apples represent one for each day, without mentioning the doctor. This shows that the student has partially seen the pattern but missed the deeper joke. Another tendency is to overcomplicate the story and imagine hidden emotions or events that are not in the text. In exam situations, always look first for a simple explanation that ties together every important detail, especially specific numbers and familiar phrases.

Final Answer:
The bus driver gives Sana seven apples because of the proverb that says an apple a day keeps the doctor away, so the correct explanation is Because an apple a day keeps the doctor away.
