Which Gana did Gautam Buddha belong to?

Correct option is B

The correct answer is (b) Sakya.
Explanation:

• Gautam Buddha, the founder of Buddhism, belonged to the Sakya clan, which was a small republic or Gana in ancient India.
  
• He was born as Siddhartha Gautama in Lumbini (present-day Nepal) in the Sakya Gana, and his father was the ruler of the Sakya tribe.
  
•  Lichchavi, Moriya, and Malla were other prominent clans or Ganas in ancient India, but Buddha was not a part of these.

He understood the Four Noble Truths and the Eightfold Path, which form the core teachings of Buddhism:
1. The truth of suffering (Dukkha).
2. The cause of suffering (Samudaya).
3. The cessation of suffering (Nirodha).
4. The path to the cessation of suffering (Magga).
Thus, the correct answer is (b) Sakya.
