To whom Gautam Buddha gave his last sermon at Kushinagar?

The correct answer is (a) Subhadda.

Subhadda was a wandering monk who came to visit Gautama Buddha on his deathbed. The Buddha gave Subhadda a brief sermon on the Four Noble Truths and the Eightfold Path. This sermon is known as the Mahaparinirvana Sutra.

Ananda was the Buddha’s personal attendant and one of his closest disciples. Sariputra and Upali were also two of the Buddha’s most important disciples. However, there is no record of the Buddha giving his last sermon to any of them.

The Four Noble Truths are:

1. Suffering exists.
2. Suffering is caused by attachment.
3. Suffering can be ended.
4. The way to end suffering is to follow the Eightfold Path.

The Eightfold Path is:

1. Right understanding
2. Right thought
3. Right speech
4. Right action
5. Right livelihood
6. Right effort
7. Right mindfulness
8. Right concentration

The Mahaparinirvana Sutra is one of the most important texts in Buddhism. It contains the Buddha’s final teachings on the nature of reality and the path to liberation.
