Explanation: To understand the context of the question, it is essential to consider the geographical and time zone aspects of India. Arunachal Pradesh is located in the easternmost part of India, while Gujarat is in the westernmost part. Due to this geographical difference, the sun rises earlier in Arunachal Pradesh compared to Gujarat. This is a natural phenomenon based on the Earth's rotation and the longitudinal difference between the two regions.
However, the statement that watches show the same time in both regions is also true. India follows a single time zone, known as Indian Standard Time (IST), which is based on the longitude of 82.5°E, passing through Allahabad. This means that despite the geographical difference, all regions in India, including Arunachal Pradesh and Gujarat, follow the same time.
The misconception that the watches showing the same time is the correct explanation for the earlier sunrise in Arunachal Pradesh is incorrect. The watches showing the same time is a separate fact that does not explain the sunrise difference. The earlier sunrise in Arunachal Pradesh is due to its geographical location, not because of the time zone policy.
In summary, the sun rises earlier in Arunachal Pradesh compared to Gujarat due to its geographical location, and the watches showing the same time is a separate fact due to India's single time zone policy. Therefore, the correct answer is that the statement A is true, but the statement R is false. This understanding is crucial for comprehending the geographical and time-related aspects of India's diverse regions.
