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.

1. Statement 1: The use of gunpowder was known in India before the arrival of Babur, particularly in regions like the Deccan and Gujarat. However, Babur is credited with the effective use of field artillery and gunpowder tactics on a large scale, which played a crucial role in his victories. The statement claiming *introduction* is generally considered incorrect, although he significantly enhanced its military application. Hence, Statement 1 is incorrect. 2. Statement 2: The arch and dome were key elements of architecture introduced in India during the Delhi Sultanate period, long before Babur's arrival. Various mosques, tombs, and forts built during the Sultanate era showcase these features. Hence, Statement 2 is incorrect. 3. Statement 3: Babur traced his lineage back to Timur (Tamerlane) on his father's side. The dynasty he founded in India, the Mughal dynasty, is considered a branch of the Timurid dynasty. Thus, his conquest led to the establishment of a Timurid dynasty in the region. Hence, Statement 3 is correct. 4. Therefore, only statement 3 is correct.
