Which of the following place is famous for its gigantic rock-cut statue of Buddha?

Answer: Option A

* Bamiyan: This site, located in Afghanistan, was famous for its two massive statues of Buddha carved into the side of a cliff.
While tragically destroyed in 2001, it's historically known for these giant Buddha figures.

* Borobudur: This is a large Buddhist temple in Indonesia, but it's a complex structure with many stupas and carvings, not a single gigantic rock-cut statue.

* Anuradhapuram: This ancient city in Sri Lanka has many Buddhist monuments and ruins, but isn't primarily known for a single giant rock-cut Buddha statue.

* Angkor Wat: This is a massive temple complex in Cambodia, originally dedicated to the Hindu god Vishnu and later used as a Buddhist temple.
It is famous for its intricate carvings and scale, but not a giant rock-cut Buddha statue.

Therefore, Bamiyan is the place most associated with gigantic rock-cut statues of Buddha.
