1.Which Chinese Nobel Prize Winner author's wife is kept under house arrest by the Chinese government to refrain other nation's delegates from meeting her to congratulate on her husband's success ?

Liu Xiaobo, the Chinese Nobel Peace Prize winner in 2010, had his wife Liu Xia placed under house arrest by the Chinese government. She was detained to prevent foreign diplomats and dignitaries from meeting her to congratulate her on her husband's Nobel Prize. Liu Xiaobo was imprisoned at the time and could not attend the ceremony in Norway. Note: The option spells it as 'Liu Xiabao' but should be 'Liu Xiaobo' (spelling error in option).
