Correct Answer:
A. 1885, Karachi
Sindh Madrassa-tul-Islam was a pivotal educational institution founded in 1885 in Karachi by Hassanally Effendi. It played a crucial role in the educational upliftment of Muslims in the Sindh region, providing modern education alongside religious teachings. Option A is correct as it accurately identifies both the year and the city of its establishment. Options B, C, and D are incorrect because they either misstate the founding year or the city. For instance, 1890 and 1895 are incorrect years, and Lahore was not the city where this specific madrassa was founded.
