The correct answer to the question is option 3, Sharqi rulers.

To understand why the Mosque is associated with the Sharqi rulers, we need to know a bit about their history. The Sharqi dynasty was a Muslim dynasty that ruled over the Eastern region of India, particularly in the 14th and early 15th centuries. The rulers of this dynasty were known for their patronage of art, culture, and architecture.

During their reign, the Sharqi rulers constructed numerous mosques as a symbol of their power, religious devotion, and architectural achievements. These mosques were not only places of worship but also served as important cultural and social centers in their respective cities.

While the Sultans of Delhi, Mughal rulers, and Rohilla rulers also played significant roles in the history of India, they are not specifically associated with the construction of mosques. It is important to note that the question is asking for the association of the Mosque with a particular ruling dynasty, which is the Sharqi rulers in this case.

Therefore, the correct answer is option 3, Sharqi rulers.
