Correct option is C
The correct answer is: (C) Bodh Gaya
Gautama Buddha attained enlightenment under the Bodhi tree at Bodh Gaya in present-day Bihar, India. This is where, after meditating for several days, he achieved profound insight into the nature of suffering and the path to its cessation, which forms the foundation of Buddhist teachings.
- Sarnath: This is the place where Buddha gave his first sermon after attaining enlightenment, known as the "Dharma Chakra Pravartana" (the turning of the wheel of Dharma).
- Pavapuri: This is the place where Mahavira, the 24th Tirthankara of Jainism, attained nirvana, not where Buddha attained enlightenment.
- Kushinagar: This is the place where Buddha passed away and attained parinirvana (final nirvana after death).
