请教下各位一道语法题：
A star will compress itself into a white dwarf, a neutron star, or a black hole after it passes through a red giant stage, depending on mass. 全句划线
(A) A star will compress itself into a white dwarf, a neutron star, or a black hole after it passes through a red giant stage, depending on mass.
(B) After passing through a red giant stage, depending on its mass, a star will compress itself into a white dwarf, a neutron star, or a black hole.
(C) After passing through a red giant stage, a star’s mass will determine if it compresses itself into a white dwarf, a neutron star, or a black hole.
(D) Mass determines whether a star, after passing through the red giant stage, will compress itself into a white dwarf, a neutron star, or a black hole.
(E) The mass of a star, after passing through the red giant stage, will determine whether it compresses itself into a white dwarf, a neutron star, or a black hole
为什么这题选D呢,
我认为D项中的意思表达是：质量决定一个星星是否会压缩成白矮星中子星或者黑洞?而我认为根据A作者想表达的意思是质量决定一个星星变成一个 白矮星中子星还是黑洞，强调“决定变成哪一种”，这不是改变了句意吗？
A项不懂哪里错了?
求助解答,非常谢谢！！！！ 作者: brfmzbjz 时间: 2014-7-8 18:21
A 逗号+depending 修饰前面的句子 it passes through a red stage
意思错
D determins whether a star will compress itself into a A, B, or C.
意思就是你说的 决定了星星是否会变成A，B，或者C中的一种
