Where did the Buddha attain nibbana?

Kusinagara

The correct answer is Option (4) → Kusinagara

Buddhist literature mentions several chaityas. It also describes places associated with the Buddha’s life – where he was born (Lumbini), where he attained enlightenment (Bodh Gaya), where he gave his first sermon (Sarnath) and where he attained nibbana (Kusinagara). Gradually, each of these places came to be regarded as sacred. About 200 years after the time of the Buddha, Asoka erected a pillar at Lumbini to mark the fact that he had visited the place.
