Step 1: Identify Gautama Buddha’s birthplace.
Gautama Buddha, founder of Buddhism, was born in 563 BCE. His birthplace is recorded as Lumbini, situated in present-day Nepal.
Step 2: Eliminate wrong options.
- (B) Vaishali: Important Buddhist center, but it is where Buddha gave his last sermon.
- (C) Sarnath: The place where Buddha delivered his first sermon (Dhammachakra Pravartana).
- (D) Bodh Gaya: The site where Buddha attained enlightenment under the Bodhi tree.
Step 3: Conclusion.
Thus, Buddha was born at Lumbini, not at Vaishali, Sarnath, or Bodh Gaya.
