[求助] 为什么这里可以用现在完成时？

261. Being a United States citizen since 1988 and born in Calcutta in 1940. author Bharati Mukherjee has lived in England and Canada, and first came to the United States in 1961 to study at the Iowa Writers' Workshop.

(C) Born in Calcutta in 1940, author Bharati Mukherjee became a United States citizen in 1988; she has

 (D) Being born in Calcutta in 1940 and having been a United States citizen since 1988, author Bharati Mukherjee

(E) Having been born in Calcutta in 1940 and being a United States citizen since 1988, author Bharati Mukherjee

刚刚在做菜鸟手册，此题的答案是C。我赞同答案所解释的，ABDE均有明显缺陷，但是C也有明显缺陷啊。如果没有结尾的HAS，或者HAS改成HAD，我肯定选C了，但是就因为这个HAS我一上来就把C排除掉：因为显然Bharati Mukherjee 住在英国和加拿大是在去美国之前的事，应该用过去时或者过去完成时啊。为什么这里可以用HAS？我实在百思不得其解。 小弟初来乍到，初次发贴，还请各位大虾不吝指教。

B为什么错啊
