The system of 'Dagh' (branding of horses) and 'Chehra' (descriptive roll of soldiers) was first introduced by whom?

Correct answer: Alauddin Khalji

Explanation: ✅ Correct Answer: D) Alauddin Khalji 📚 Explanation: Alauddin Khalji introduced these military reforms to prevent corruption, such as the substitution of superior horses with inferior ones or the hiring of proxies during inspections. 'Dagh' ensured that only state-approved horses were maintained, while 'Chehra' provided a detailed physical description of every soldier. These systems allowed the Sultan to maintain a highly disciplined and efficient standing army capable of resisting Mongol invasions.
