The correct answer is option 2: Bangkok. The Erawan shrine, which experienced a significant bomb blast in August 2015, is located in Bangkok, the capital city of Thailand. The Erawan shrine is a well-known Hindu shrine that is visited by locals and tourists alike. It is situated in the downtown area of Bangkok, near the busy intersection of Ratchaprasong.
Option 1, Singapore, is incorrect because the Erawan shrine is not located in Singapore. Singapore is a separate country located in Southeast Asia.
Option 3, Kuala Lumpur, is also incorrect. Kuala Lumpur is the capital city of Malaysia and does not have the Erawan shrine.
Option 4, Kabul, is incorrect as well. Kabul is the capital city of Afghanistan and is not the location of the Erawan shrine.
In conclusion, the Erawan shrine, which was the site of a major bomb blast in August 2015, can be found in Bangkok, Thailand.
