Scientists in which of the following countries were successful in creation of Human Embryo by the process of cloning?

South Korea is correct. In 2005, South Korean scientist Hwang Woo-suk claimed to have created human embryonic stem cells through cloning, though this was later exposed as fraudulent. However, at the time this question was written, it was considered correct. Japan has had notable achievements in cloning, but the major human cloning controversy of that era centered on South Korean scientists.
