Gautam Buddha gave his first sermon at which of the following places?

Sarnath

The correct answer is Option 1- Sarnath

Gautam Buddha gave his first sermon at Sarnath, India. Sarnath is a suburb of Varanasi, and it is one of the four most holy Buddhist pilgrimage sites.

The other options are incorrect because:

• Lumbini is where the Buddha was born.
• Kapilavastu is where the Buddha grew up.
• Vaishali is a city in India where the Buddha gave many sermons, but it is not where he gave his first sermon.

The Buddha's first sermon is known as the Dharma chakra parivartan, or the Sermon on Turning the Wheel of the Dharma. In this sermon, the Buddha taught the Four Noble Truths and the Eightfold Path.
