Antarctica receives more solar radiation than does any other place on Earth, yet the temperatures are so cold and the ice cap is reflective, so that little polar ice melts during the summer; otherwise, the water levels of the oceans would rise 250 feet and engulf most of the world’s great cities.

A.     is reflective, so that little polar ice melts during the summer; otherwise,

B.      is so reflective that little of the polar ice melts during the summer; were it to do so,

C.     so reflective that little polar ice melts during the summer, or else

D.     reflective, so that little of the polar ice melts during the summer, or

E.      reflects so that little of the polar ice melts during the summer; if it did

The answer is B. But I am wondering what does the "it" in B refer to?

C might be better?

B.      is so reflective that little of the polar ice melts during the summer; were it to do so,

分词后面的这句话是虚拟语气，表示与前面所陈述的事实相反，were it to do so, 就是it were to do so,it没有什么指代问题，指先前所陈诉的事实，就是说事实如果是先前所陈述（Antarctica receives more solar radiation than does any other place on Earth）的那样的话，～～～～

C.     so reflective that little polar ice melts during the summer, or else

the temperatures are so cold 和 the ice cap is so reflective that little of the polar ice melts during the summer是两句并列的句子，C选项将后半句的谓语给抽除了，显然错误，or else其逻辑含义也、含糊不清

it 好像不能指代整句话吧......所以你说的“指先前所陈诉的事实”我觉得错误了吧

1.
I think "it" refers to " the ice cap".
"were it to do so"  means:
if the ice cap were not so reflective that ... , the water levels would ....

2.
Option C is a fragment without a verb.
