Consider the following : The arrival of Babur into India led to the 1. introduction of gunpowder in the subcontinent 2. introduction of the arch and dome in the region's architecture 3. establishment of Timurid dynasty in the region Select the correct answer using the code given below.

Option (B) is correct because Babur, a direct descendant of Timur, established the Timurid (Mughal) dynasty in India following his victory at the First Battle of Panipat in 1526. Statements 1 and 2 are incorrect because gunpowder was already in use in India by the 14th century (notably in the Deccan and Gujarat), and the arch and dome were introduced much earlier by the Delhi Sultanate in the 12th-13th centuries. The core concept tested is the chronological accuracy of technological, architectural, and political developments during the transition from the Sultanate to the Mughal era.
