In which of the following Mudra did Gautam Buddha delivered his first sermon at Saranath?

The correct answer is: Dharmachakra Mudra.

The Dharmachakra Mudra is a symbolic gesture that represents the turning of the wheel of dharma, or the teaching of the Buddha. It is made by placing the right hand on the left thigh, with the palm facing up and the fingers pointing down. The index finger and thumb are extended and joined together to form a circle.

The Dharmachakra Mudra is often used in Buddhist art and iconography to represent the Buddha’s first sermon at Sarnath, in which he taught the Four Noble Truths. It is also used in Buddhist ceremonies and rituals to represent the Buddha’s teachings and to invoke his blessings.

The other options are:

• Abhaya Mudra: This mudra is made by raising the right hand with the palm facing outward and the fingers extended. It is a gesture of reassurance and protection.
• Dhyana Mudra: This mudra is made by placing the hands in the lap, with the right hand on top of the left and the palms facing up. It is a gesture of meditation and concentration.
• Bhumisparasa Mudra: This mudra is made by touching the earth with the right hand. It is a gesture of humility and respect.
