The National Emblem of India has been adopted from the capital of King ___________________ which was situated in ___________________ .

The correct option is Ashoka, Sarnath.

Step-by-step Explanation:
1. The Lion Capital: The National Emblem of India is a representative model of the Lion Capital of Ashoka. The original sculpture features four Asiatic lions standing back-to-back on an elaborate circular base (abacus).
2. King Ashoka and Sarnath: This monolithic pillar capital was commissioned by the Mauryan Emperor Ashoka around 250 BCE. It was placed atop the famous Ashoka Pillar in Sarnath, near Varanasi in Uttar Pradesh, marking the sacred location where Lord Buddha delivered his first sermon (known as the Dharmachakrapravartana or "Turning of the Wheel of Law").
3. Symbolic Significance: Below the lions, the abacus features a wheel in the center (the Ashoka Chakra), flanked by a bull (representing steadfastness) and a galloping horse (representing speed and energy), which are separated by smaller wheels. India officially adopted this symbol as its state emblem on January 26, 1950, to represent authority, peace, and power.
