请大家帮忙看两题

鹊儿喜

(A)

(E) Due to their capability to reproduce several  times  yearly  and  to produce large numbers of offspring,many insect species

答案选E, 感觉A也没什么语法错误

In Newtonian laws of motion, there is a condition and it's converse regarding bodies at rest and bodies in motion.

(B) In Newtonian laws of motion, there is a condition and its converse regarding bodies at rest and bodies in motion

(C)In Newtonian laws of motion, there are a condition and its converse regarding bodies at rest and bodies in motion

答案是 C,感觉此题的考点很诡异，B 和C 的差异仅在it's 和its上，用its没有疑问，但是究竟是there is 还是there are，请教大家，依答案的选择，莫非 a condition and its converse 是不可分的，不符合就近指代的原则？是这样吗？
