答案：
B
选B.
主干是
Travelers would have to endure ..., avoiding ..., plus contending .., and ward off.逻辑为：旅行者从地球到火星将不得不忍受低重力，避免辐射，加上与化学反应的竞争，甚至可能阻止..的污染。原文4个动作平行，逻辑合理，但语法错误，plus不是连词，未划线部分的ward off和前面的contending，avoiding，endure不平行。
B项endure，avoid，content，ward off平行。
C项跳过having to endure，谓语接的是would also have to avoid ，改变逻辑，且和后面的ward off不平行。
D项同C，跳过having to,谓语改变，plus不是连词。
E项缺谓语，改变逻辑。
