A. All dynasties depended on effective use of firearms on the battlefield and in siege warfare.

Explanation:

All major empires of human history were built through military might, at least substantially. In these three cases, not all of them were of Mongol descent; there may have been important numbers of Christians in the Ottoman Empire but that was not the case in Mughal India and the Safavids; Hinduism, and not Islam, was the religion of the majority in India under the Mughals.

The three empires were run by Mulsi
