Which is the birth place of Budha?

Lumbini, located in present-day Nepal, is the birthplace of Siddhartha Gautama, who later became known as the Buddha. Kushinagar is where Buddha attained Mahaparinirvana (death), Darjeeling is a hill station in India, and thus the correct answer is Lumbini. This is a well-documented historical and geographical fact about Buddha's origins.
